This historical dataset is recommended for ancillary use only and not as a primary research dataset. It has likely been superseded by a newer, improved dataset.
Abstract:
The Cross-Calibrated Multi-Platform (CCMP) data product is derived through cross-calibration and assimilation of ocean surface wind data from SSM/I, TMI, AMSR-E, SeaWinds on QuikSCAT, and SeaWinds on ADEOS-II. Cross calibration is performed by Remote Sensing Systems (RSS) under the DISCOVER project. These data sets are combined with conventional observations and a starting estimate of the wind field using a variational analysis method (VAM). The ECMWF Reanalysis (ERA-40) is used as the starting estimate (or background) for July 1987 until December 1998 and the ECMWF Operational Analysis is used from January 1999 onward.
CCMP is provided by the NASA PO.DAAC and has been evaluated and utilized extensively by the science community, including some members of NASA's Ocean Vector Winds Science Team (OVWST).

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
