GOES-17 (GOES-West) Upper-level Water Vapor (6.2 µm) images (above) include contours of Moderate Or Greater (MOG) Turbulence Probability and Pilot Report... Read More

The latest release of the CSPPGeo software package geo2grid (version 1.1, downloadable here) includes support to display two Level 2 products from GOES-R: Cloud Top Temperature and Cloud Top Height. Cloud Top Temperature, above, created using data ordered and downloaded from the NOAA CLASS site, is at 2-km resolution (in line with the latest... Read More

IntenseStormNet is a part of the ProbSevere portfolio; it relates ABI Channels 2 (0.64 µm) and 13 (10.3 µm) and GLM observations of Flash Extent Density (see this past blog post for more information) to the likelihood that a given satellite-detected storm is severe. (The probabilities are created from output of a Convolutional Neural... Read More
