GOES-17 visible and infrared imagery shows Tropical Storm Estelle over the eastern Pacific to the west-southwest of Baja California. Although there are regions of strong convection, satellite presentation of the storm suggests a modest tropical storm. Center-fixing a storm such as this (with just one image vs. an animation!) is...

In a previous post, we explored a data interpolation technique that involved running sections of missing GOES-17 Band 13 data through a shape-preserving piecewise cubic spline method in order to fill the data gaps for brightness temperature (BT). (That method was nicknamed ‘pchip’ interpolation.) In this post, we introduce a more... Read More

GOES-18 images shown in this blog post are preliminary and non-operational Overlapping 1-minute Mesoscale Sectors provided 30-second images of GOES-18 “Red” Visible (0.64 µm) data, which showed the circulation of a Mesoscale Convective Vortex (MCV) that moved northward across southern Nevada early in the day on 17 July 2022. Ongoing thunderstorms along the periphery... Read More

1-minute Mesoscale Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.35 µm) and Fire Temperature RGB images (above) showed a wildfire just southwest of Yellowknife (CYZF) in Canada’s Northwest Territories, which produced a pyrocumulonimbus (pyroCb) cloud during the afternoon hours on 12 July 2022.This large fire burned very hot,...
