RSS CCMP Monthly 10 Meter Surface Winds Level 4 Version 3.1
(CCMP_WINDS_10MMONTHLY_L4_V3.1)| Version | 3.1 |
| Processing Level | 4 |
| Start/Stop Date | 1993-Jan-01 to Present |
| Short Name | CCMP_WINDS_10MMONTHLY_L4_V3.1 |
| 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. |
