The animation above shows convection over the south Pacific to the east of American Samoa (note the Manu’a Islands just east of 170 W Longitude in the animation). Extensive cloud cover will limit the ability of the GOES-17 instrument to detect low-level cloud motions underneath the deep convection, which motions... Read More

GOES-17 (GOES-West) Shortwave Infrared (3.9 µm) images (above) included plots of hourly surface temperature during the 26 June – 27 June 2021 period — the first 2 days of a historic heatwave across the Pacific Northwest (caused by an anomalous 500hPa ridge over the region). Numerous high temperature records were set, including new all-time record highs for... Read More

GOES-16 (GOES-East) “Red” Visible (0.64 µm), Near-Infrared “Snow/Ice” (1.61 µm), Near-Infrared “Cloud Particle Size” (2.24 µm), Shortwave Infrared (3.9 µm) and Fire Temperature RGB images along with Fire Temperature, Fire Power and Fire Area derived products (above) showed reflectance and thermal signatures of sunlight reflecting off large arrays of solar panels at solar farms across southern/central Minnesota...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched plots of SPC Storm Reports — and showed severe thunderstorms across eastern Colorado, western Kansas and far southwestern Nebraska late in the day on 19 June 2021. Numerous pulsing overshooting tops were evident with many of these storms. Wind gusts to 88 mph were reported in KansasThe corresponding 1-minute GOES-16... Read More
