Visible Infrared Imaging Radiometer Suite (VIIRS) data from Suomi NPP and NOAA-20 can be used to create accurate sea-surface temperature (SST) fields using the Advanced Clear-Sky Processor for Ocean (ACSPO) algorithms. The toggle above shows ACSPO SSTs over the Gulf of Maine from Suomi NPP (at 0620 UTC) and from NOAA-20 (at 0710 UTC) — orbital paths can be found here. Waters... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed a long-lived Mesoscale Convective System (MCS) or derecho that produced a swath of large hail and damaging winds (SPC Storm Reports | NWS Nashville) from eastern Kansas to central Tennessee, northern Mississippi and northern Alabama on 03 May 2020.The corresponding GOES-16 “Clean” Infrared Window (10.35 µm)...

Overlapping 1-minute Mesoscale Domain Sectors provided GOES-16 (GOES-East) “Red” Visible (0.64 µm) images at 30-second intervals (above) — which showed rapidly-developing thunderstorms over northeastern Oklahoma, southeastern Kansas and southwestern Missouri on 28 April 2020. These storms developed along and ahead of an approaching cold front, and produced large hail and damaging winds (SPC Storm Reports).The corresponding 30-second GOES-16... Read More
Nishinoshima is a small volcanic island (at 27.2471° N, 140.8779° E) about 150 km west of Chichijima.) Nishinoshima has grown in size over the past decades because of volcanic activity, including activity (apparently accompanied by occasional earthquakes) that started in March 2020. Day Night Band imagery from NOAA-20, above, (toggled with an annotated image) shows the light from... Read More
