Enhanced QuikSCAT Wind Processing at NOAA/NESDIS for Accurate Near-Real-Time Results

The improvements in QuikSCAT near-real-time wind processing implemented at NOAA/NESDIS include changes in model function for higher wind speed retrievals, enhanced processing of measurements at the swath edge, revised rain flagging reducing from 4.2% to ~1.8%, and the introduction of the QuikSCAT_P 25km, and QRad Rain Rate Product. These enhancements aim to provide more accurate and reliable wind data for forecasting and research applications.

  1. Improvements in QuikSCAT Near-Real Time Wind Processing Implemented at NOAA/NESDIS Zorana Jelenak, Paul S Chang and Michael J Brennan* NOAA/NESDIS/STAR *NWS/NHC

  2. Changes in Model Function → Higher Wind Speed Retrievals Change made at 16m/s

  3. Change in Processing of the Measurements at the Swath Edge→ Improved Retrievals Correct ambiguities chosen in new processing

  4. Change in Rain Flag → rain flagging reduced from 4.2% (old) to ~1.8% (new) QuikSCAT 25km QuikSCAT_P 25km

  5. New QRad Rain Rate Product → Will be Available in NAWIPS and Web Page
