GOES-18 (GOES-West) Upper-level Water Vapor (6.2 µm), Mid-level Water Vapor (6.9 µm), Lower-level Water Vapor (7.3 µm) and “Clean” Infrared Window (10.3 µm) images (above) revealed the diurnal cycle of nighttime cooling and daytime warming at the summits of Mauna Kea and Mauna Loa on the Big Island of Hawai’i on 10 January 2023. In addition, a hot thermal... Read More
From GOES-A (1) in 1975, to GOES-T (18) launched in 2022! On January 4, 2023 GOES-18 is operational as GOES-West, here’s a look-back at all the GOES. Note that the GOES-R series imagers support the generation of a true color image, given they have the blue (or 0.47 micrometer) band. Continuity is critical for operational satellites... Read More
Heavy rains have finally hit California, which declared a state of emergency on Wednesday January 4 due to extreme rainfall amounts. The GOES-West enhanced Band 9 imagery (6.9 µm, mid-level water vapor) illustrates how moisture associated with the recent similar Trans-Pacific atmospheric river generated heavy rainfall for much of California, Oregon, and...
