A GOES-17 airmass RGB, above, shows a strong feature in the Gulf of Alaska. It’s common to associate the orange and purple regions within that polar feature (that is accompanied by cloud features consistent with very cold air aloft) with enhanced ozone.

GOES-16 (GOES-East) Near-Infrared “Snow/Ice” (1.61 µm) images (above) showed the shadow of a total solar ecliipse in the Southern Hemisphere on 04 December 2021. Even though the 1.61 µm imagery is at a lower (1 km) spatial resolution, it provided better contrast than higher-resolution (0.5 km) 0.64 µm “Red” Visible imagery, helping to highlight... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed thunderstorms that produced a variety of severe weather (SPC Storm Reports) across far southern Oklahoma on 22 April 2020. These discrete supercell storms developed along a cold front associated with a low pressure system moving across the region (surface analyses).GOES-16... Read More
A sequence of GOES-17 (GOES-West) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) showed the evolution of a bomb cyclone (surface analyses: WPC | OPC) that made landfall along the Oregon/California coast just after sunset on 26 November 2019. The storm produced wind gusts of 106 mph in southwestern Oregon... Read More
