The Advanced Scatterometer (ASCAT) sensor onboard the EUMETSAT MetOp polar-orbiting satellite provides ocean surface wind observations by means of radar scatterometry. The data is available as 1-day composites with global coverage at 0.25 degrees (approximately 25 km/pix). Total wind speed, as well as zonal and meridional wind speed information is available since 2013-06-26 through the present.

The dataset contains satellite-derived ocean wind speed, stress and stress curl measurements collected by means of the NASA/JPL SeaWinds Scatterometer sensor. The data is collected daily, and is available at 3-day, weekly and monthly intervals at a spatial resolution of approximately 0.5 degrees. The geographic coverage extends globally, and the temporal coverage ranges from 1999-2009.

These data depict the predicted mean annual wind speed in meters per second at 100 meters elevation above sea level. The source data is from 2007 through 2013, and is based on a 2 km sample resolution. The source data was generalized and transformed into a polygon format for planning purposes.

These data represents the predicted mean annual wind speeds at 90 m height presented at a spatial resolution of 200 m. Areas with annual average wind speed of 7 meters per second (m/s) and greater at 90 m height are generally considered to have a wind resource suitable for offshore development. The source data is from 2002 through 2008.

CCMP_RT V2.1 has been created using the same VAM as CCMP V2.0 Input data have changed and now include all V7 radiometer data from RSS, V8.1 GMI data from RSS, scatterometer data from RSS (V4 QuikSCAT and V1.2 Advanced SCATterometer (ASCAT)), NO buoy data, and National Centers for Environmental Prediction (NCEP) GFS 0.25 degree data for the background field.

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.

NOAA CoastWatch distributes science quality Ekman current (in zonal, meridional, and modulus sets) and Ekman upwelling data. This data begins with wind velocity measurements from the ASCAT instrument onboard EUMETSAT's Metop-A satellite. ASCAT is a microwave scatterometer designed to measure surface winds over the global ocean. NOAA CoastWatch processes wind velocity to wind stress and wind stress curl, and finally to Ekman current and Ekman upwelling. (This is a monthly composite.)

These raw data have not been subjected to the National Ocean Service's quality control or quality assurance procedures and do not meet the criteria and standards of official National Ocean Service data. They are released for limited public use as preliminary data to be used only with appropriate caution.
