Sentinel-1A overflew the Samoan Islands on 4 September — as it does every 12 days — and the Normalized Radar Cross Section data (as at this website) was used to create wind data at very high spatial resolution. Sentinel-1A derived wind data can also be viewed at this NOAA/STAR website that has links... Read More
Overlapping 1-minute Mesoscale Domain Sectors provided GOES-16 (GOES-East) images at 30-second intervals from all 16 of the ABI spectral bands (above), which displayed the northeast-moving bright reflectance and/or the warm thermal signature of a SpaceX Falcon 9 rocket booster as the Crew-7 Mission was launched from Cape Canaveral Space Force Station in Florida at 0727...

GOES-18 (GOES-West) Mid-level Water Vapor (6.9 µm) images (above) included plots of 1-hour Precipitation Accumulation — which showed rainfall associated with the northward spread of moisture across the Southwest US as Tropical Storm Hilary made landfall in Baja California on 20 August 2023. A similar animation with plots of 6-hour Precipitation Accumulation is... Read More
