The direct broadcast antenna at the NWS forecast office on Guam processed important information to show details of Typhoon Bolaven as it passed through the Marianas Islands on 10 October. The toggle above compares VIIRS band M07 (0.865 ) and Rain Rate derived from ATMS imagery at 0338 UTC, when the typhoon was east of Guam. It passed between... Read More
Direct Broadcast antennae give timely full-resolution imagery from various Low-Earth-Orbit satellites as they move within the view of the satellite received. Community Satellite Processing Package (CSPP) software takes the downloaded signal and produces imagery (or AWIPS-ready files). The toggle above shows VIIRS (Visible-Infrared Imaging Scanning Radiometer) and ATMS (Advanced Technology Microwave Sounder) data from... Read More
This recent blog post highlighted an Advanced Microwave Scanning Radiometer (AMSR-2) product showing estimates of Sea Ice concentration at high spatial resolution. This followup post shows the product on a different day in 2022. The MODIS True-Color imagery below, from March 22, 2022, shows ice in the Bering Sea and Arctic Ocean surrounding... Read More
Widespread clouds can easily hide the location of active precipitation. When that happens, well-timed microwave information can show where precipitation is most likely. In the slider example above, Aqua MODIS infrared imagery with a grey-scaled enhancement (collected over Guam just before 0350 UTC on 9 July) shows regions of convection west and south of Guam (circled in yellow). Where are the heaviest rains located, and... Read More
