The Cross-Calibrated Multi-Platform (CCMP) Ocean Surface Wind Components time series has been extended through 30 June 2011. This additional year of data extends the CCMP climate data record (CDR) by 6 months, for a total of 24 years, starting on 1 July 1987.
Due to the loss of QuikSCAT’s ability to retrieve wind vectors since 22 November 2009, the CCMP analysis through 2011 does not assimilate any scatterometer vector wind data. Additionally, SSM/I data from DMSP F13 has been unavailable since 19 November 2009. To help make up for the loss of wind observations, CCMP has included the WindSat polarimetric radiometer wind speed data from Remote Sensing Systems (REMSS). SSM/IS data from DMSP F17 have also been assimilated starting in 2010. It is worth noting that F17 and WindSat share a very close orbital ground track with a local time separation of approximately 28 minutes at the equator. This relatively close orbit proximity of F17 and WindSat results in a more limited resolution of synoptic and transient features.
The AMSR-E data used in the CCMP analysis has been upgraded by REMSS from version 5 to version 7. This upgrade is effective in the CCMP analysis from 1 January 2011 through the latest analysis time. For more details on this upgrade, please visit: http://www.ssmi.com/amsr/amsr_data_description.html
