Outline• Prepare for GOES-R high temporal water vapor

measurements for high impact weather (HIW) forecasting through data assimilation;– MODIS TPW, AMSR-E TPW, and GOES Sounder PW as proxy– WRF/DART, WRF/3DVAR

• Improve high impact weather forecasts with advanced IR soundings;

• Verify impact with in-situ measurements, hurricane track and intensity observations, GOES Imager, and microwave measurements;

• 2012 plan – value added impact on HIW forecasts with advanced IR soundings when combining GOES-R and polar sounders.

AIRS soundings provide value-added information to conventional observations(Track forecast RMSE for hurricane Ike - 2008)

AIRS single FOV soundings in clear skies are used. WRF/3DVAR (12 km resolution) forecasting and assimilation system is used. Assimilation is done every 6 hours. 0-h is from analysis, others are forecasts (06 UTC 06 September 2008 – 00 UTC 10 September 2008).

4. Summary and 2012 plans• GOES Sounder, MODIS, AMSR-E TPW as proxy for GOES-R

shows positive impact on HIW forecasts;• Advanced IR soundings provide positive impact on tropical cyclone

intensity and track analysis/forecasts;• WRF/DART and WRF/3DVAR provide consistent results;• 2012 plans on HIW studies

– Use GSI to emulate operational environment; focus on using GOES Sounder for preparing GOES-R applications;

– Study value added impact with advanced IR soundings (radiances or retrievals) on HIW forecasts when combining GOES-R and polar-orbiting sounders;

– Continue collaboration with ESRL RAP modeling group;– Collaborate with JPSS sounding team (Chris Barnet) on using AIRS/CrIS

(including AMSU and ATMS).
