High Density Cloud Drift Winds
This product displays wind speed and direction at different altitudes (100-400 mb, 400-700 mb, and below 700 mb) using infrared data from geostationary satellites. It's created by tracking infrared energy signatures and guidance from numerical weather forecasts, available in both hemispheric and mercator projections.
SAR High Resolution Coastal Winds
The APL/NOAA SAR Wind Retrieval System (ANSWRS) converts SAR NRCS measurements into wind speed values at a 500m spatial resolution, similar to scatterometers but applied on a per-image basis as imagery is received.
RADARSAT-2 | Resolution: 500 m | Frequency: Approximately 10 images each day
High Density Cloud Drift Winds
Jason-3 wind speeds are estimated from the shape and intensity of the altimeter radar echo, representing ~2-5 km footprint depending on sea state, to within 1.6 meters/second.
OSTM/Jason-3 | Resolution: ~300m along track (20 Hz)/~7km along track (1Hz) | Frequency: 10-14 times each day
ASCAT Winds
The Advanced Scatterometer (ASCAT) provides 10-meter neutral stability winds, processed by NOAA/NESDIS using EUMETSAT's MetOp satellite data. Wind fields are detailed within 30x20 degree bins, accessible through an HTML link map. Click on a location for a closer view. This system partly compensates for QuikSCAT winds. Global wind images represent data from the past 22 hours at two resolutions: 25 Km and 50 Km.
POES | Resolution: 12.5 - 25 Km | Frequency: 3 Minute Granules
Sea Surface Wind Speed
The GCOM-W project is a 13-year mission with a series of three satellites that aims to measure global-scale water-cycle changes over a long period of time. The GCOM-W1 is the first satellite in the GCOM-W series and was launched in May 2012 by the Japan Aerospace Exploration Agency (JAXA).
