  1. Recent Progress on High Impact Weather Forecast with GOES‐R and Advanced IR Soundings Jun Li1, JinlongLi1, Jing Zheng1, Tim Schmit2, andHui Liu3 1 University of Wisconsin-Madison 2 Center for Satellite Applications and Research, NESDIS/NOAA 3 National Center for Atmospheric Research Warn-on-Forecast and High Impact Weather Workshop 08 – 09 Feb 2012, Norman, OK

  2. 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.

  14. OBS CTL AIRS-TQ Hurricane at 2008090606 CTL AIRS-TQ CTL:radiosondes, satellite winds, pilot report, GPS, ship, profiler, surface observations AIRS-TQ: CTL + AIRS-TQ

  15. 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).

  16. 72-hour ensemble forecasts – Hurricane Irene (2011) (from 06 UTC 23 to 00 UTC 25 August 2011) Assimilation method: WRF/DART with 36 km resolution Control (CTL): assimilate radiosonde, satellite cloud winds, QuikSCAT winds, aircraft data, COSMIC GPS refractivity, ship, and land surface data; AIRS: CTL + AIRS temperature and moisture soundings CTL AIRS Obs Irene (2011) track forecasts Irene (2011) sea level pressure forecasts

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).
