Using a combined LEO/GEO approach, ABI and VIIRS retrievals are used to estimate flooding from a satellite perspective. Individual flood products from VIIRS and ABI (or AHI, depending on location) are blended to create the NOAA LEO/GEO Flood Mapping Product.An example is shown below over the... Read More
SAR data are being acquired over American Samoa for the next several weeks. SAR data from a Sentinel-1A overpass at 0553 UTC on 31 January, shown above (from this website), shows mostly light winds, mostly less than 10 m/s. The Normalized Radar Cross Section (NRCS) data can be used to view any ice contamination in the wind speed image.... Read More
GOES-16 (GOES-East) “Red” Visible (0.64 µm) images which include plots of GOES-16 Derived Motion Winds within the Suface-900 hPa layer (above) showed the eastward transport of several ice floes from the northern portion of Green Bay into Lake Michigan on 30 January 2023. Surface wind gusts and Derived Motion Wind speeds were generally in the... Read More
An animation of the Day Cloud Type RGB over Lake Superior on 30 January 2023, above, shows two prominent features: persistent lake-effect bands oriented west-northwest to east-southeast over the western four-fifths of the Lake (station KCMX on the Keewenaw peninsula, for example, observed heavy snow during this animation), and a more north-south oriented convergence band that extends from the eastern Upper Peninsula of...
