1. 1 Numerical Weather Prediction Subcommittee Chairs: Ralph Petersen/Mark DeMaria MEMBERS NESDIS/ORA: Bob Aune, Paul Menzel, Tim Schmit, Dan Tarpley NESDIS/OSD: Jim Gurka NOAA/FSL: Dan Birkenheuer, Steve Koch CIRA/CSU: Jim Purdom

2. 2 NWP Tasks Identified at the 2001 GOES Users Conference –Develop prioritized list of Imager and Sounder products (both individual and combined) u Consider complement to other satellite (polar, etc) –Determine needs of data distribution for NWP u Latency versus quality u Impact of data compression –Develop plan for coordination with JCSDA –Investigate possibility for targeted observations –Workshop focused on NWP issues

3. 3 NWP Developments Since 2001 Meeting –No formal meeting of NWP subcommittee u Informal meetings among some members –Imager/Sounder Data and Products u Plan for regional models with 0.5-2 km resolution, global models 10-20 km horizontal resolution, both with 100-200 vertical levels u Model focus on radiance data, some products u Short-term/Nowcasting focus on products u 4 km HES highly desirable u Need cloud information, vertical moisture structure –Use imager data to assist with cloud/clear distinction u Surface properties/emissivity required u Combined GOES/Polar radiances/products u HES experience being gained with AIRS data

4. 4 NWP Developments Since 2001 Meeting –Data distribution needs for NWP u Issues for NWP still need to be addressed u Experience with channel sub-sampling being gained with AIRS data u Data compression issues being addressed by other sub- committees –Coordination with the JCSDA u JCSDA beginning to take shape u Announcement of Opportunity for first year funding released u Coordinate through involvement of NWP subcommittee co- chairs and members

5. 5 NWP Developments Since 2001 Meeting –Targeted observations u Allowances should be made in system design u Details of coordination between NWP centers and NESDIS operations need to be worked out –Could follow model of current GOES RSO periods –Workshop on GOES-R and NWP u None specifically for GOES-R, but many on-going related activities –ECMWF annual moisture workshop –AIRS conference (NCEP, NASA, NESDIS, ECMWF, UKM) –WRF model data assimilation sub-group –JCSDA efforts –New Issue: NOAA’s new mandate for air quality forecasting should be addressed u Will require “optional” ABI channels
