Hourly GOES-18 Hemispheric views, above, from 2140 UTC on 1 December to 2040 UTC on 4 December, (from the CSPP Geosphere site) show the development of a strong system in the Gulf of Alaska. This system is tapping into an airstream rich in moisture that augurs for a wet period along the... Read More
In July 2022, significant flooding affected metropolitan St. Louis as multiple convective cells trained through the area. (This blog post contains clean window imagery for 26 July portion of the two-day event; the St Louis WFO also discussed the event). This WPC discussion describes the atmospheric setup on 25 July. A retrospective model run for this flooding event was created... Read More
Hourly GOES-West imagery from the CSPP Geosphere site, above (direct link to animation), shows the development of a broad Kona Low over the Hawai’ian islands. MIMIC Total Precipitable Water (TPW) fields over the eastern Pacific, below, show a very moist airmass moving into the eastern Hawai’ian islands as the Kona low develops to the west. The OSPO Percent of Normal fields at 1200... Read More
The Community Satellite Processing Package (CSPP) allows a user to manipulate VIIRS data to create high-quality, full-resolution imagery (see, for example, this I05 example, and this Day Night Band example, and this I01 example). In addition to single-band images, imagery for products such as Advanced Clear Sky Processor for Ocean (ACSPO) sea-surface temperatures (SSTs) can also be created, as shown above. Polar2grid software... Read More
