The TROPICS constellation of satellites was augmented by a final launch of two cubesats from the Mahia Rocket Launch site at the south end of the Mahia Peninsula on the east coast of New Zealand’s North Island on 26 May 2023. GOES-18 visible imagery, above, stepping from 0320 to 0350 UTC on 26 March,... Read More
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Fire Temperature RGB and “Clean” Infrared Window (10.3 µm) images (above) showed the intensification of 3 wildfires in northeast British Columbia on 20 May 2023. Two of the fires produced pyrocumulonimbus (pyroCb) clouds, exhibiting cloud-top 10.3 µm infrared brightness temperatures of -50ºC or colder (shades of red) — which then eventually moved eastward...

GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images (above) showed the formation of a pyrocumulonimbus (pyroCb) cloud — produced by a wildfire southwest of Fort Nelson, British Columbia (station identifier CYYE) — around 2340 UTC on 19 May 2023. Cloud-top infrared brightness temperatures reached -61ºC as the pyroCb cloud drifted eastward across Alberta.GOES-18 True... Read More
