Description

This data set contains a monthly-mean, 0.25 degree resolution, near-global gridded analysis of ocean surface winds (wind speed, components, and anomalies) from the Cross-Calibrated Multi-Platform (CCMP) project. CCMP is a combination of inter-calibrated 10 m ocean surface wind retrievals from multiple types of satellite microwave sensors and a background field from reanalysis. The wind retrievals are derived by Remote Sensing Systems (RSS) and include most of the wind-sensing U.S., Japanese, and European satellites flown to date. The background field is from ERA5 10m Neutral Stability winds. The result is a product that remains closely tied to the satellite retrievals where they are available and closely collocated in time and space. Data files are available in netCDF format, with one file per month.

Version 3.1 updates include but are not limited to: (1) Improved performance and agreement with satellite winds at high wind speed, (2) Minimized spurious trends caused by the interaction between the amount of satellite measurements available and the satellite/model biases, and (3) improving the quality of the wind after 2012.

Version 3.1 is produced and maintained by RSS with support from a NASA grant (ROSES proposal 17-OVWST-17-0023). Previous versions were funded by the NASA Making Earth Science data records for Use in Research Environments (MEaSUREs) program, with the original V1.0 led by Dr. Robert Atlas at Goddard Space Flight Center.

Variables

The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.

For questions on a specific variable, please use the Earthdata Forum.
