Aqua and Terra MODIS true color imagery shows two areas of significant smoke today: across parts of the Pacific Northwest region of the US, and also across parts of Quebec and Labrador in eastern Canada (northeast of the cloud shield that is the remnants of Tropical Storm Ernesto... Read More
Areas of radiation fog were forming during the overnight hours in the river valleys of southwestern Wisconsin, southeastern Minnesota, and northeastern Iowa. These narrow finger-like fog features were apparent on the MODIS 11-3.9 micrometer “fog/stratus product” (upper left panel) due the higher spatial resolution (1 km IR) and better spectral...

One of the important changes made to the GOES-N/O/P series of satellites is the addition of increased onboard battery capacity to enable the satellites to continue to provide imager and sounder data during the Spring and Fall season “eclipse periods”. During these eclipse periods (which can last 1-3 hours), the... Read More
Tropcal Storm Ernesto moved inland over southern Florida this morning, and was downgraded to a Tropical Depression. The AWIPS image below shows a MODIS vs. GOES comparison of the longwave IR (“IR Window”) and shortwave IR channels around 16 UTC. Note on the 1-km resolution MODIS IR... Read More
