THIS PROJECT IS TO UPDATE AND EXTEND THE OCEAN VECTOR WIND CLIMATE DATA RECORD. IT WILL INCLUDE UPDATES TO VERSION 8 OF THE SENSOR-SPECIFIC CDRS FOR QUIKSCAT, WINDSAT, AND ASCAT-A WHILE ALSO INCLUDING EXTENSIONS TO ASCAT-B, RAPIDSCAT AND SCATSAT-1. EFFORTS WILL ALSO BE MADE TO IMPROVE THE TUNING/CALIBRATION OF GMFS THROUGH INCLUSION OF SST-DEPENDENCE AT KU-BAND, HIGH-WIND SPEED CALIBRATION THROUGH USE OF SMAP, AND CORRECTIONS RELATED TO RAINFALL. EXTENSIVE INTERCALIBRATION OF ALL SENSOR-SPECIFIC CDRS IS ALSO TO BE UNDERTAKEN. SCIENCE ANALYSES WILL BE PERFORMED WITH RESPECT TO DIURNAL CYCLE VARIABILITY THROUGH LEVERAGING THE CONSTELLATION OF SCATTEROMETERS AND RADIOMETERS.
