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

A recent blog post detailed a heavy rain event over the Kona section of Hawai’i, and the rain occurred several hours after NOAA-20 overpasses that included an unfortunately-placed data gap that included the Big Island of Hawai’i. Thick clouds over the region meant geostationary satellites could not provide information about the thermodynamics surrounding Hawai’i. The image below shows the early morning NOAA-20 orbits on this day. The pass just after 1100 UTC was far... Read More

Target Sector (2.5-minute interval) JMA Himawari-9 Visible and Infrared images (above) covered the period when Typhoon Mawar reached Category 4 intensity at 0000 UTC on 23 May 2023 (JTWC advisory | SATCON | ADT). Mesovortices within the eye were evident in the Visible imagery, and cloud-top infrared brightness temperatures surrounding the eye were... Read More
