MDE Product Development Team – September 2009thFY 2009 4 Quarter ReportSubmitted 15 October 2009With contributions from Geoff DiMego and Mary Hart (NCEP/EMC);Stan Benjamin, John Brown, Steve Weygandt (NOAA/ESRL/GSD);Jordan Powers, Roy Rasmussen (NCAR);and Ming Xue (OU/CAPS)(Compiled and edited by S. Benjamin and B. Johnson)Executive SummaryMDE report at AWR Program Mgmt Review (Sept 2009)– Task 09.5.1: Infrastructure support related to operational running of the RUC and NAM operationalmodeling systems.Testing underway at NCEP for 18h RUC, also including adding Canadian aircraft (non-turboprop) reports,fix to cloud analysis for warm clouds, TAMDAR moisture data in NCEP RUC restored on 14 Oct.Task 09.5.4Develop, test, and implement Rapid Refresh configuration of the WRF modeling system. Changes made to WRF model and bug-fix to cloud analysis involving MPI improve RR robustness with 1h cycling and eliminate spurious features in forecast reflectivity. New file system became available, greatly alleviating the serious file-system problems on ESRLsupercomputer; RR 1-h cycle now much more reliable. Partial cycling for Rapid Refresh running in primary 1-h cycle at GSD, giving much improved results Improvements in WRF-RR: testing of WRFV3.1.1 and options in 1-h cycle Continued real-time feed of RR files to other AWRP RTs and Alaska Region NWS and getting feedbackfrom them.Task 09.5.5:Develop, test, and implement 3DVARs for RR and NAM Sept - GSI code change to upgrade to FY09 version (with all RR features added) and to move cloudanalysis after variational solver and add removal of super saturation and negative moisture. Preliminaryresults for cloud analysis changes suggest improved short-term ceiling / visibility forecasts. RR GSI – completion of elevation correction for surface obs to match model value, retrospective testnearly complete; work underway on coastline regime-dependent background for assimilation of surfaceobs. Visit by GSD to NCEP in August - discussions between GSD and NCEP on GSI changes for RR cloudanalysis after initial RRTask 09.5.6:Improve WRF model WRF Version 3.1.1 released in July, changes underway toward next versionTask 09.5.8:Improve RR/RUC model physicsnd 2 moment Thompson microphysics implemented into primary RR (operRR) on 27 August.Task 09.5.15: Develop methods for improved cloud/hydrometeor analysis in RR Discussions on GOES cloud data for full RR domain including Alaska (replacing CONUS GOES clouddata). NASA Langley cloud top data (covering almost all of the RR domain) now being used in parallel RR cycleat GSD.1

Task 09.5.24/19: Begin 3km High-Resolution Rapid Refresh testing / Improve radar assimilation Continued evaluation of larger-domain HRRR over eastern 2/3 CONUS. HRRR moved to new file system – 17 August 2009 – reliability much improved. Initial test of CONUS-domain HRRR conducted on new, faster nJet computer. Three papers presented on HRRR at WSN09 symposium and 1 paper at AMS radar conference Completion of HRRR reflectivity verification at coarsened resolution confirms that scores just afterconvective initiation improve substantially when allowance is made for small phase errors Completion of initial 3-km radar assimilation experiment for a test case -- encouraging results.Test 09.5.20 Probabilistic forecasts Initial VSREF framework developed by NCEP/EMC using code from RCPF for convective module Additional GSD progress on a time-lagged HRRR-based convective probability forecastTask 09.5.1Infrastructure Support Related to Operational running of the non-WRF Rapid Update CycleSystem in NCEP OperationsGSDTesting of 18h RUC with changes at NCEP underway, conducted by NCEP/EMC with new code from ESRL/GSD.Key components: Extension of hourly RUC forecasts from 12h out to 18h every hour (i.e., new forecasts with hourly outputto 18h to be produced in every RUC cycle 24x/day). Addition of Canadian aircraft data (see below), often over 1000 reports/hour. Previously, Canadianaircraft was from turboprop planes, with poor heading information and poor quality wind data. However,reports from those aircraft are now excluded (by Canada), leaving regional jet data of high quality. Correction to saturation of 3-d volumes with warm clouds. This problem was detected in late April afterinvestigating a problem with RUC data reported by WSI. A fix was made to the GSD RUC versions atthat time, and now is being added to the operational RUC at NCEP. As part of the RUC testing, it was found in early September that the TAMDAR moisture observations werenot being used in the operational RUC (and NAM) even though they were properly assimilated back inNovember 2008 as part of the RUC upgrade. GSD and NCEP investigated this issue, found that it wasrelated to a metadata change made to TAMDAR data, and a fix was implemented on 14 October,restoring it to the operational RUC and NAM.GSD modifications to experimental ESRL RUC for the July-Sept period Assimilation of Canadian aircraft data. Obs-background differences were re-examined for these dataand found to now be of good quality. Canadian aircraft contribute a large number of observations, over1000 reports/hour. Therefore, Canadian aircraft were added to the devRUC in early August and to thebackup RUC in late August. Assimilation of NASA Langley cloud data. Langley began producing hourly GOES-based cloud fields(top pressure, top temperature, liquid water path, ice water path) over most of the Rapid Refresh domain.Code was developed to assimilate this larger-domain data into the RUC, and was implemented into thedevRUC at ESRL in early August and into the backup RUC in late August. Similar changes wereintroduced into the similar cloud analysis code in the GSI used in the parallel Rapid Refresh in earlyOctober (see Task 5.15). This is the first assimilation of cloud-top data over Alaska. Discussions withNESDIS and NASA Langley occurred on testing a proposed new NESDIS cloud product to allowcomparisons with the Langley product. Use of PBL depth in the radar reflectivity assimilation was introduced into the dev RUC in Sept 2009 as aproxy for cloud base. If shown to be beneficial overall, this will be introduced to the backup RUC andcounterpart RR radar assimilation code.NCEPDetails below from Dennis Keyser and Geoff Manikin.Geoff Manikin began work on extending the operational Rapid Update Cycle to 18 hours. The current RUCconfiguration features runs to 12 hours every third cycle (0000 UTC, 0300 UTC, etc) and to 9 hours for all inbetween cycles. The new configuration will have all 24 cycles run to 18 hours. A parallel cycle has been set up2

to make sure that there are no model problems with the extended run time and to also be certain that all extraproducts are successfully created. This code will be turned over to NCEP Central Operations soon in hopes of alate fall implementation.Subtasks09.5.1.1 Maintain hourly RUC runs and provide aviation guidance grids. (30 Sept 09)There were no issues related to RUC aviation performance this quarter. (Manikin)09.5.1.2 Provide vendors with gridded model data via Family of Services (FOS), and the FAA Bulk Weather DataTelecommunications Gateway (FBWDTG). (30 Sept 09)NCEP maintained real-time availability of SAV and AIV guidance to all vendors from the operational hourly RUCon pressure surfaces on the 80-km AWIPS grid #211 via the NWS Family of Services (FOS) data feed and theFAA Bulk Weather Data Telecommunications Gateway (FBWDTG). (EMC Team and NCO/PMB/Dataflow Group)09.5.1.3 Provide full grids from RUC runs on NCEP and NWS/OPS servers. (30 Sept 09)NCEP maintained real-time availability of full resolution gridded data from the operational RUC runs viaanonymous ftp access via the NCEP server site /prod/ and at the NWS/OPS site atftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/ in hourly directories named MT.ruc CY.00 throughMT.ruc CY.23. This includes hourly BUFR soundings and output grids which undergo no interpolation. Bothsites now contain only grids packed into GRIB2 format, seehttp://www.nco.ncep.noaa.gov/pmb/docs/GRIB1 to GRIB2.shtml. A limited set of fields from the RUC runs(and other NCEP models) can also be viewed /. (EMC Team and NCO/PMB/Dataflow Group)09.5.1.4 Maintain access to model verification data. (30 Sept 09)NCEP maintained its capability and provided access to routine verifications of the operational RUC analyses andforecasts. These include grid-to-station verifications versus rawinsonde, surface, aircraft, Profiler, and VAD datacomputed periodically at NCEP and accessible via NCEP’s Mesoscale Modeling Branch (MMB) meso.verf.html This capability was enhanced in December2008 when Julia Zhu combined the various routine verification jobs and scripts and worked with NCO/PMB tohave them added to the operational NCEP Production Suite. This combined processing runs more reliably inProduction and is automatically switched with the rest of the suite when it is necessary to failover operations fromone computer to another. (EMC Team and NCO/PMB)Deliverables09.5.1E1(30 September 2009)(Manikin, Keyser, Liu)Perform ingest, quality control and preparation of both existing and new observations in support of the operationalRUC runs.CURRENT EFFORTS: NCO is investigating an invalid instrument type reported by some radiosonde sites.Incorrect elevations for many radiosonde and surface sites in the NCEP station dictionaries were updated on 4August. All sources of TAMDAR data that were shut off on 7 April returned on 6 July after NWS and AirDATreached a new agreement. Work restarted on getting TAMDAR airframe type and airline codes into thePrepBUFR file for ESRL’s bias correction work. TAMDAR data were not decoded on 20-26 August due to anunadvertised change in the MADIS NetCDF files; the NCO decoder was updated on 26 August and TAMDARadded to the “critical” tracking list. GSD discovered in late September that the 20 August MADIS changes alsoresulted in no TAMDAR moisture data being decoded at NCEP since then. This problem was corrected on 14October. Results from the new NRL-based aircraft QC code were compared to the existing QC code for twoweeks in August; the new code is superior so NCEP will switch to it sometime this fall. The transition of3

observation ingest, dump and quality control and processing codes and scripts to the P6 computer wassuccessfully completed on 12 August. See CURRENT EFFORTS listed under Task 09.5.17.E1 below for finalresults. Some drifting buoys are not being decoded properly when they have a missing station pressure; NCO islooking into this problem. An updated version of the NCEP BUFR library software is being tested for a fallimplementation. NESDIS hasn’t yet responded to two problems with the GOES 1x1 field-of-view cloud datawhere a few random files begin with reports encoded with missing lat/lons and a bogus satellite ID and whereGOES-East data arrives later. The quality of SSM/I products from the operational F-13 satellite began to degradein early August due to instrument problems. (Keyser)EMC is testing code to assimilate Canadian aircraft data in the RUC to accompany the U.S. TAMDAR data. Thisnew code will be part of the extension to 18 hour implementation (see 09.5.1E2) later this fall. (Manikin)PLANNED EFFORTS: See also PLANNED EFFORTS listed under Task 09.5.17.E1 below for aircraft qualitycontrol issues. Obtain all TAMDAR data from AirDAT as alternate to MADIS feed and add airframe type andcompany code to allow improved bias corrections to be developed. (Keyser)PROBLEMS / ISSUES ENCOUNTERED OR ANTICIPATED: A critical shortage of disk space on the new P6computers.INTERFACE WITH OTHER ORGANIZATIONS: NCO.UPDATES TO SCHEDULE: Complete.09.5.1E2(30 September 2009)(Manikin)Perform configuration management for RUC, including thorough documentation, and respond promptly to anycode malfunctions or performance issues.CURRENT EFFORTS: Work is underway to extend the RUC to 18 hours for all cycles, at the request of AWCand SPC. The new configuration (along with a few bug-fixes) is now running in parallel at EMC. (Manikin andESRL)PLANNED EFFORTS: The RUC code will be handed off to NCO in October and a late fall implementation islikely. (Manikin)PROBLEMS / ISSUES ENCOUNTERED OR ANTICIPATED: Lack of disk space on the new computer.INTERFACE WITH OTHER ORGANIZATIONS: NCO.UPDATES TO SCHEDULE: Complete.09.5.1E3(30 September 2009)(Manikin, Keyser)Monitor RUC performance, respond to any problems detected by ESRL, NCEP, or any RUC users, diagnosecause, develop solution to RUC software, test changes and coordinate with NCO on implementation.CURRENT EFFORTS: EMC developed a code fix to address a problem identified by a user this past summer.During the cloud assimilation, when a grid point is identified as "cloudy", the water vapor mixing ratio is increased,but the virtual potential temperature is not adjusted upward accordingly. As a result, when a user attempts to devirtualize this potential temperature, the resulting value is far too cold. This fix is part of the RUC upgrade with the18h extension package (Manikin and NCO/PMB)PLANNED EFFORTS: Add this correction to the RUC 18 hour extension implementation. Continue monitoringefforts.PROBLEMS / ISSUES ENCOUNTERED OR ANTICIPATED: None.INTERFACE WITH OTHER ORGANIZATIONS: NCO.4

Benjamin, Stephen S. Weygandt, Ming Hu (presented by Stan Benjamin)Task 09.5.17 Infrastructure support for operational running of WRF-based modeling system in NorthAmerican Mesoscale and HiResWindow at NCEP.NCEPEric Rogers continued running the NOAA Environmental Modeling System (NEMS)-based NDAS/NAM real-timeparallel system on the P6 supercomputer (which took over operational production on 18 August). Several fixeswere installed in various codes to remove egregious errors and improve performance. Additionally, a fullretrospective capability with the NEMS-based system was built and used to run several case studies ofproblematic operational NAM forecasts to help assess performance.In the WRF-NMM NDAS/NAM parallel, degraded performance (higher upper level temperature biases) led to thetemporary removal of two bug fixes to the microphysics installed in July: 1) a dummy variable representing themean mass of large ice particles (snow) was instead the first-guess mean diameter of the ice particles. This bugoccurs only when the first-guess number concentrations of large ice particles are outside of a predefined range;and 2) enforce a minimum number concentration for large ice particles (1 per liter) at all temperatures, rather thannot enforcing it at 0C in the operational code where a fixed mean diameter is assumed. Examination of the skillscore time series showed that the first change was causing the higher temperature bias, which disappeared whenit was removed. The second change had no adverse impact and will be reinstated in early September. NCO hasgiven a tentative implementation date for this minor bug fix bundle of 13 October.Since many obs-processing activities listed under Task 09.5.1 also pertain to NAM, they are not duplicated here.For the NAM specifically, Dennis Keyser reports there are errors in the mesonet wind uselist provider listings,which caused the loss of over 600 sites in the NAM-GSI. A request to correct the uselist was submitted in Augustafter NCO’s moratorium ended. Some Alaskan radiosonde sites still need to move up their launch time so theNAM-GSI can use their data. A request (from May) to add NOAA-19 1B HIRS-4, AMSU-A and MHS radiances tothe 1B ingest and dumps, is awaiting implementation by NCO (hopefully in September). Consultation withNESDIS revealed that NCEP’s logic for checking the calibration flag for ATOVS HIRS-3 and HIRS-4 radiances isincorrect. When the flag is set, NCEP currently disregards all channels instead of checking the calibration qualityfor each channel and allowing good channels to be used. This change was tested in the parallel GSI and is5

included with the NOAA-19 change request package. The following data types are monitored by the NAM-GSI:RASS virtual temperature profiles (NPN and MAP), QuikSCAT 0.5 deg. scatterometer wind superobs, Mesonetmass data, and MDCRS moisture data. A final comparison of observational dump counts between the P5 (Dew)and P6 (Stratus) computers (before the P6 took over operational production on 18 August) showed generally thesame number of observational data in both from the NCO-based decoders (which handle mainly non-satelliteobservations), slightly more satellite data in the P6 dumps (mainly due to their being ingested more frequently),and slightly less Level II NEXRAD radial wind data. The cause of the lower P6 NEXRAD dump counts is beinglooked into. Crons are generating NAM/NDAS PrepBUFR files with 50 km ASCAT and WindSat scatterometerwind data (both non-superobed) and NAM/NDAS dumps of METOP IASI radiances, GPS-RO data and SBUV-2data. These changes to obs monitoring plus several NMM bug-fixes are being tested in Eric Rogers’ real-timeparallel NDAS/NAM. Tests are underway to evaluate the impact of using the GFS tropical cyclone relocationprocedure to update the global first guess fields input to the t-12 hour NDAS in medium to strong tropical cyclonecases. This could replace the current synthetic wind data bogus. Efforts continue to remove a legacy restrictionthat surface data must have a pressure report to be processed into the PrepBUFR files. This will allow many newsurface observations (land, marine and Mesonet) to be assimilated in the RTMA. The geographical domain forthe RTMA dumps, currently the same as the expanded NAM domain, will soon expand to include the Guamregion.Subtasks09.5.17.1 Maintain four-per-day North American Mesoscale runs and provide aviation guidance grids. (30 Sept09)The real-time NAM parallel continues to run on the CCS, testing minor bug fixes in the WRF-NMMdynamics/physics and a change in the cloud microphysics that leads to more realistic GOES brightnesstemperature lookalike output from the NAM post-processor. In early August, parallel verification statistics showeddegraded performance (higher upper level temperature biases), which led to the temporary removal of two bugfixes to the microphysics installed in July: 1) a dummy variable representing the mean mass of large ice particles(snow) was instead the first-guess mean diameter of the ice particles. This bug occurs only when the first-guessnumber concentrations of large ice particles are outside of a predefined range; and 2) enforce a minimum numberconcentration for large ice particles (1 per liter) at all temperatures, rather than not enforcing it at 0C in theoperational code where a fixed mean diameter is assumed. Examination of the skill score time series showed thatthe first change was causing the higher temperature bias, which disappeared when it was removed. The secondchange (which removed spurious snow at the surface) had no adverse impact and was reinstated in earlySeptember. (Rogers)The NDAS/NAM system using the NEMS/NMMB model, the NEMS Preprocessing System (NPS), the NMMBversion of the GSI analysis, and the unified NCEP post-processor continues to run in a real-time parallel on theCCS. Numerous modifications and bug fixes have been made to this run during this period of testing, which canbe considered a “shakedown” of the system. Most of the changes made were to move the NEMS/NMMB parallelcloser to the operational NDAS/NAM configuration (similar resolution and number of grid points, increaseddivergence damping during the NDAS NMMB forecast, fixes to the update of the model sea ice using the dailyNESDIS sea-ice analysis). (Rogers)09.5.17.2 Maintain four-per-day HiRes Window runs and provide aviation guidance grids. (30 Sept 09)A set of script changes for the operational HiresW system were submitted on 28 September. Over the previousmonth there had been several non-reproducible failures in the HiresW as different parts of the overall jobconflicted with each other at the script level. These failures generated product delays as the jobs had to bererun. The submitted changes separate the components of the system more cleanly, and should make theHiresW more robust and its product delivery timelier. (Pyle)NCEP maintains 4/day runs of WRF-NMM at 4 km and WRF-ARW at 5 km when there are no hurricane runs.Five domains are run with three large domains - Eastern CONUS (00z & 12z), Western CONUS (06z) and Alaska(18z), and two small domains - Hawaii (00z & 12z) and Puerto Rico (06z &18z). For most of this quarter, theHiResWindow runs were made since there were few tropical systems to cause preemption. NCEP also maintainstwice-per-day runs of six WRF-based members (3 running NMM and 3 running ARW) of the Short Range6

Ensemble Forecast (SREF) system with aviation guidance available ml which now includes specific output for Alaska andHawaii (eastern Pacific). (Pyle, Du and NCO)09.5.17.3 Provide vendors with gridded NAM model data via Family of Services and the FAA Bulk Weather DataTelecommunications Gateway. (30 Sept 09)NCEP maintained real-time availability of SAV and AIV guidance to all vendors from the operational 4/day NAMon pressure surfaces on the 80-km AWIPS grid #211 via the NWS Family of Services (FOS) data feed and theFAA Bulk Weather Data Telecommunications Gateway (FBWDTG). Higher resolution grids (40-km grid #212 and12-km grd #218) are also made available to FOS (and NOAAPORT) users. (EMC Team and NCO)09.5.17.4 Provide full grids from NAM, and the HiRes Window on NCEP and NWS/OPS servers. Maintain accessto model verification data. (30 Sept 09)NCEP maintained real-time availability of full resolution gridded data from the operational 4/day NAM andHiResWindow (HRW) suite of WRF-NMM and WRF-ARW runs via anonymous ftp access via the NCEP serversite at rod/ (on numerous grids) and at the NWS/OPSsite at ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/. At the NWS/OPS site, the NAM data are in 4/daydirectories named MT.nam CY.hh where hh 00,06,12 or 18; while the HRW data are in 4/day directories namedMT.hires MR.mmm CY.hh where mmm arw or nmm and hh 00,06,12 or 18. This includes hourly BUFRsoundings (NAM only) and output grids which undergo little or no interpolation. Both sites now contain only gridspacked into GRIB2 format, see http://www.nco.ncep.noaa.gov/pmb/docs/GRIB1 to GRIB2.shtml. HRWoutputs were added to NOAAPORT feed this quarter and will become available to NWS forecast offices withAWIPS OP9. A limited set of fields from the NAM and HiResWindow (HRW) runs (and other NCEP models) canalso be viewed at http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/. (EMC Team and NCO/PMB/DataflowGroup)09.5.17.5 Working with NCO, complete the design, compilation, debugging, test runs and parallel testing of NAMand HRW (and SREF) codes on new CCS computer. (30 Sept 09)NCEP’s new computer system in Gaithersburg, MD and Fairmont, WV was declared operational and beganproducing NWS forecast guidance on 12 August. The NCO moratorium on model upgrades ended on 18 August,2009.Deliverables09.5.17.E130 September 2009EMC (Rogers, Pyle, Keyser, Liu)Perform ingest, quality control and preparation of both existing and new observations in support of the operationalWRF runs.CURRENT EFFORTS: In addition to the items reported in 09.5.1E1, some Alaskan radiosonde sites still need tomove up their launch time so the NAM-GSI can use their data. A final comparison of observational dump countsbetween the P5 and P6 NCEP computers (before operational production switched to the P6 on 18 August)showed generally the same number of observations from the NCO-based decoders (which handle mainly nonsatellite observations), slightly more satellite data in the P6 dumps (mainly due to their being ingested morefrequently), and slightly less Level II 88D radial wind data. The lower P6 Level II 88D dump counts are beinginvestigated. Some drifting buoys are not being decoded properly when they have a missing station pressure.NCO is looking into this. Errors in the mesonet wind uselist provider listings were corrected on 25 August, makingover 600 new sites available for assimilation by the NAM-GSI. NOAA-19 was added to the HIRS-4, AMSU-A andMHS 1B radiance ingest and dumps on 29 September, and is being tested in the parallel NAM-GSI. Logic forchecking the NESDIS calibration flag for HIRS-3 and HIRS-4 radiances in the NCEP ingest was corrected on 29September. The ingest now checks the calibration quality for each channel, allowing individual “good” channelsto be passed. This change will prevent significant outages, like on 9 July (18 hours) for METOP-2 HIRS-4 and on6-7 July (13 hours) for NOAA-17 HIRS-3. The 29 September change package also increased the reportedradiance lat/lon accuracy for all ATOVS 1B instruments and satellites from 0.01 to 0.0001 degrees, which had7

positive results in GBL-GSI tests. NESDIS reduced instrument noise and bias by changing their GOES imagerand sounder patch temperatures from their warm season to cold season set-points for GOES-11 and -12 on 15and 23 September, respectively. The following data types are monitored by the NAM-GSI: RASS virtualtemperature profiles (NPN and MAP), QuikSCAT 0.5 deg. scatterometer wind superobs, mesonet mass data, andMDCRS moisture data. NAM/NDAS and RTMA PrepBUFR files are being generated with 50 km ASCAT andWindSat scatterometer wind data (both non-superobed) and NAM/NDAS dumps of METOP IASI radiances, GPSRO data and SBUV-2 data. These changes to obs monitoring are being tested in Eric Rogers’ real-time parallelNDAS/NAM. Using the GFS tropical cyclone relocation procedure (in medium to strong tropical cyclone cases) toupdate the global first guess fields input to the t-12 hour NDAS is being tested as a possible replacement for thecurrent synthetic wind data bogus. Efforts continue to remove a legacy restriction that only surface data with areported pressure is processed into the PrepBUFR files. This will allow many new surface observations (land,marine and Mesonet) to be assimilated in the RTMA and possibly NAM/NDAS. The geographical domain for theRTMA dumps will soon expand beyond the NAM domain to include Guam. (Keyser)PLANNED EFFORTS: Use AIRS AMSU-A radiances in the next NAM-GSI update (assimilation stopped in April2008 when channel 4 went bad). Add a new aircraft quality control module from NRL once NCO evaluation isfinished and run times are improved. Change PrepBUFR processing to add report sub-type information so theanalysis can develop bias corrections based on data sub-types (airframes and ascent/descent tags, mesonetproviders and sub-providers, radiosonde instrument type and on-site correction indicators). Complete impacttests in NAM for several new data types: TAMDAR (from AirDAT feed); mesonet mass and roadway data, andnew mesonet data feeds (including “hydro”, “snow”, modernized COOP, UrbaNet and late-arriving mesonet data);MDCRS aircraft moisture; NPN and MAP RASS virtual temperature profiles; JMA, European and MAP profilerwinds; GOES 3.9 micron and visible satellite winds; WindSat and ASCAT scatterometer wind data; METOP IASIradiances; ozone from NOAA-series SBUV-2 and METOP GOME-2; GPS radio occultation data; SSM/I andTRMM/TMI rain rate; METEOSAT-9 IR and visible satellite winds; NOAA-19 AMSU-A, MHS and HIRS-4radiances. Coordinate with the field to speed up more Alaskan RAOB processing. Maximize Alaska dataretrievals (especially mesonet, aircraft and coastal surface). Add GSI events to the NAM PrepBUFR files. LetGSI use the actual or estimated anemometer, barometer and thermometer heights on ships. Generate and QChigh vertical-resolution aircraft profile data near airports. Work with NCO to bring in new sources of radar data(TDWR, Tail Doppler Radar from hurricane hunter P3 aircraft, Canadian, CASA). Examine possible use ofmixed-satellite (Aqua and Terra) MODIS winds which have better coverage and timeliness than the current singlesatellite (Aqua-only or Terra-only) MODIS winds.

FAA Bulk Weather Data Telecommunications Gateway (FBWDTG). (EMC Team and NCO/PMB/Dataflow Group) 09.5.1.3 Provide full grids from RUC runs on NCEP and NWS/OPS servers. (30 Sept 09) NCEP maintained real-time availability of full resolution gridded data from the operational RUC
