GOES-18 airmass RGB imagery, above (created using geo2grid software), shows the development of a hurricane-force low to the west of Washington and Oregon on the 19th of November. The orange and purple colors in the RGB suggest a significant intrusion of stratospheric air. That air is rich in ozone, and... Read More
Mostly clear skies over the Great Lakes early on 18 November allowed for good satellite estimates of Lake Surface temperatures. They are, in a word, very warm. The toggle above compares estimates from NOAA-20 and from GOES-16. The stepped animation below (source) compares November 17th values this year with those... Read More
The Night Microphysics RGB animation from the CSPP Geosphere site (direct link to animation) below shows clouds of various heights (and temperatures). For example deep high clouds (likely precipitating) stretch northwest to southeast to the north of the Samoan Island chain. Low clouds are indicated over the three main Samoan islands: Savai’i, Upolu and... Read More
Day Night Band imagery from the three JPSS Satellites — NOAA-21 (1515 UTC), Suomi NPP (1537 UTC) and NOAA-20 (1602 UTC) show Tropical Storm Man-Yi as it approached the southern Marianas Islands early in the morning on 13 November 2024 (Guam Time).
