RADARSAT Constellation Mission One (RCM1) passed over Nepartak at 0828 UTC on 27 July 2021, and the image above shows the Synthetic Aperture Radar (SAR) winds derived at that time. There is a widespread region of ~40-knot winds (cyan to green in the color enhancement), a bit stronger than the... Read More
RADARSAT Constellation Mission 3 (RCM3) Synthetic Aperture Radar (SAR) wind data over southern Lake Michigan at 1201 UTC on 28 June, above (click to enlarge, taken from this website), shows a small region of strong winds just offshore of southeast Wisconsin and northeastern Illinois. GOES-16 Band 2 visible imagery (clipped from... Read More
The animation above shows convection over the south Pacific to the east of American Samoa (note the Manu’a Islands just east of 170 W Longitude in the animation). Extensive cloud cover will limit the ability of the GOES-17 instrument to detect low-level cloud motions underneath the deep convection, which motions... Read More
Synthetic Aperture Radar (SAR) imagery can be used to produce very high resolution mapping of winds. Imagery is available in selected domains at this NOAA/OSPO website; OSPO is the Office of Satellite Product Observations. Data are available from three different satellites: Sentinel-1/Sentinel-2 (managed by the European Space Agency) and RADARSAT (managed by the Canadian Space Agency). These space-borne radars can...
