As noted here, CSPP software now includes the ability to show reprojected values of Aerosol Optical Depth, in this case within AWIPS. The AOD from the NOAA-20 afternoon pass on 21 July shows extensive smoke over the Plains of Canada and the northern Plains of the USA. Clean air is confined to the Upper Peninsula (UP) of Michigan. The Day Night band imagery at the same time... Read More
Hurricane Beryl made a (final) landfall along the Texas Gulf Coast, near Matagorda TX, at about 4 AM CDT/0900 UTC on 8 July. VIIRS imagery, above, from the SSEC/CIMSS Direct Broadcast antenna, shows infrared (I05, 11.45 µm) imagery and Day Night Band visible (0.7 µm) imagery around the time of landfall. It is noteworthy that city lights are unable to penetrate the thick clouds (some of the reduction in... Read More
A toggle between Suomi-NPP VIIRS Visible (0.64 µm) and Infrared Window (11.45 µm) images valid at 1335 UTC on 27 June 2024 (above) showed a severe-warned thunderstorm just west of Noatak, Alaska. This thunderstorm — located north of the Arctic Circle — exhibited a cloud-top infrared brightness temperature as cold as... Read More
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Day Fire RGB, Shortwave Infrared (3.9 µm), and “Red” Visible (0.64 µm) images with overlays of the Fire Power and Fire Mask derived product (2 components of the GOES Fire Detection and Characterization Algorithm FDCA) (above) displayed signatures of the South Fork Fire and Salt Fire, which started on 17 June 2024 near Ruisodo in southern New Mexico. The GOES-18 3.9 µm Shortwave Infrared brightness... Read More
