16. AIRS Data Impact on NCEP GFS Data Category Number of AIRS Channels Total Data Input to Analysis Data Selected for Possible Use Data Used in 3D VAR Analysis (Clear Radiances) ~200x10 6 radiances (channels) ~2.1x10 6 radiances (channels) ~0.85x10 6 radiances (channels) Current preliminary impact study shows that the use of a small fraction (~0.5%) of AIRS clear only data can provide significant 3 to 6 –day forecast skill improvement in both northern & southern Hemispheres S.H. N.H.

17. JCSDA Road Map (2002 - 2010) Improved JCSDA data assimilation science 2002 2004 2007 20082009 2005 OK Required 2003 Advanced JCSDA community-based radiative transfer model, Advanced data thinning techniques Science Advance By 2010, a numerical weather prediction community will be empowered to effectively assimilate increasing amounts of advanced satellite observations 2010 AMSU, HIRS, SSM/I, Quikscat, AVHRR, TMI, GOES assimilated AIRS, ATMS, CrIS, VIIRS, IASI, SSM/IS, AMSR, WINDSAT, GPS,more products assimilated Pre-JCSDA data assimilation science Radiative transfer model, OPTRAN, ocean microwave emissivity, microwave land emissivity model, and GFS data assimilation system were developed The radiances of satellite sounding channels were assimilated into EMC global model under only clear atmospheric conditions. Some satellite surface products (SST, GVI and snow cover, wind) were used in EMC models A beta version of JCSDA community-based radiative transfer model (CRTM) transfer model will be developed, including non- raining clouds, snow and sea ice surface conditions The radiances from advanced sounders will be used. Cloudy radiances will be tested under rain-free atmospheres, more products (ozone, water vapor winds) NPOESS sensors ( CMIS, ATMS…) GIFTS, GOES-R The CRTM include cloud, precipitation, scattering The radiances can be assimilated under all conditions with the state-of- the science NWP models Resources: 3D VAR -----------------------------------------------------4D VAR 2006

18. Short Term Priorities MODIS: MODIS AMV assessment and enhancement. Accelerate assimilation into operational models. AIRS: Improved utilization of AIRS Improve data coverage of assimilated data. Improve spectral content in assimilated data. Improve QC using other satellite data (e.g. MODIS, AMSU) Investigate using cloudy scene radiances and cloud clearing options Improve RT Ozone estimates Reduce operational assimilation time penalty (Transmittance Upgrade) SSMIS: Collaborate with the SSMIS CALVAL Team to jointly help assess SSMIS data. Accelerate assimilation into operational model as appropriate

26.  Use of MODIS SST composites is currently ongoing in operational WRF forecasts  May 2004 simulations and hurricane forecasts provide the opportunity to determine the impact of MODIS SSTs on regional forecasts  Preliminary work suggests that the WRF model appears to respond appropriately to high-resolution SST data  Greatest impact of MODIS SSTs is seen in the marine boundary layer Summary
