The 10-minute full-disk imagery that is available from Himawari-8 captures the evolution of Tropical Depression 24S northwest of Australia. Convection is evolving on time-scales of 10 minutes or less, so the high temporal resolution is vital to describing the storm evolution. Of particular note are the development (and decay) of...

Satellite data are used routinely to monitor Volcanoes for eruptions that can be potential aviation hazards. The Himawari-8 false-color image, above, derived from Himawari-8 AHI data, includes a volcanic plume that, even without the image annotation, is easy to detect. Consider the same scene, below, derived from MTSAT-2 imagery. The... Read More
