10-minute Full Disk scan JMA Himawari-8 Visible, Shortwave Infrared and Infrared Window images (above) showed 2 pulses of pyrocumulonimbus (pyroCb) clouds that were spawned by a large bushfire in Western Australia on 17 November 2025. The pyroCb cloud pulses exhibited a cloud-top 10.4 µm infrared brightness temperature (IRBT) of -40ºC... Read More
As first hinted at in this blog post, the Community Satellite Processing Package for Geostationary Data (CSPP-Geo) (https://cimss.ssec.wisc.edu/csppgeo/ ) group at CIMSS has released a beta version of a unix-based package that computes LightningCast probabilities. LightningCast (available online in real time for select regions) diagnoses the probability of a Geostationary Lightning Mapper (GLM) observation of lightning within... Read More
