For this poster, forecast impacts will be compared with that of QuikSCAT surface winds. QuikSCAT winds have been proven to provide a positive forecast impact in the GFS during both seasons and in each hemisphere.
Results will be shown from a series of experiments involving GFS simulations: 1) with QuikSCAT and no WindSat, 2) without either QuikSCAT or WindSat, 3) with WindSat (windsob1°254 and windsob0.5°254) and QuikSCAT, 4) with WindSat no QuikSCAT. Quality Control (QC) techniques are developed to verify the current retrieval algorithm. The results have shown that the combination of WindSat and QuikSCAT data provides the largest positive forecast impact by day 7 in the GFS. The T254 WindSat experiments also demonstrated larger anomaly correlation gains with a 1° superob of the data than a 0.5° superob of the data. As the next step for acceptance into operations, these previously tested WindSat experiments have now entered daily real time testing at NCEP.
