SAR winds over Tropical Storm Mirinae

Tropical Storm Mirinae, shown above, to the east of Japan (click here to see the same image with latitude/longitude lines), was overflown on 8 August by Radar Constellation Mission Satellite one (RCM-1) at 2013 UTC. The Synthetic Aperture Radar (SAR) imagery (from this site) is shown below, with both polarities. The two... Read More

Comparing SAR data over Lake Superior to radar

Synthetic Aperture Radar (SAR) winds are derived from a microwave signal pinged from a satellite; backscatter is converted into winds (given a background field that is typically from a numerical model). The wind structure here is suggestive of a bowing feature to a convective downdraft. How does it compare to... Read More

SAR winds near Tropical Storm Nepartak

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
