Cross-Calibrated Multi-Platform (CCMP) 6 Hourly V02.0

The Cross-Calibrated Multi-Platform (CCMP) gridded surface vector winds are produced using satellite, moored buoy, and model wind data, and as such, are considered to be a Level-3 ocean vector wind analysis product. We have updated the CCMP product, using improved and additional input data. This web site documents the new CCMP V2.0 data set now available from Remote Sensing Systems (RSS). The V2 CCMP processing now combines Version-7 RSS radiometer wind speeds, QuikSCAT and ASCAT scatterometer wind vectors, moored buoy wind data, and ERA-Interim model wind fields using a Variational Analysis Method (VAM) to produce four maps daily of 0.25 degree gridded vector winds. The original CCMP product (V1.1) was originally produced by Bob Atlas and his team with funding from the NASA REASoN and MEaSUREs programs. The original MEaSUREs product is still available from the NASA Physical Oceanography DAAC (podaac.jpl.nasa.gov). RSS has transitioned the CCMP processing code to run using our most up-to-date satellite data observations. All methodology remains the same as that used in the original CCMP product and most of the CCMP processing code is unchanged, with only minor alterations to compensate for the different operating systems and compilers.
