Subsequently, flood warnings were issued for Kauai. The animation above (from the southwest corner of the GOES-18 PACUS domain) shows the... Read More

Metop-C and NOAA-20 are now both supplying NUCAPS profiles to National Weather Service AWIPS machines. Both the vertical profiles and gridded fields are available. The toggle above shows all the MetopC overpasses early on 4 April, and it includes horizontal maps of 850-mb Temperatures derived from the Metop-C NUCAPS profiles. Large swaths of satellite-derived fields are available... Read More

CIMSS Scientists have adjusted the presentation of individual thermodynamic variables produced from HEAP (NUCAPS) profiles for NOAA-20 overpasses that are available here in near-real time (at that website, chose j01 (that is, NOAA-20), crisfsr, and then images); HEAP software that supports NOAA-21 data is not yet available. Previously (above) values... Read More

The addition of a 2nd satellite (MetopC) producing NUCAPS profiles means that places such as Guam have twice as much Satellite information over the otherwise data-sparse western Pacific Ocean. The three-panel above shows the 1200 UTC sounding at Guam (on the left) with a nearly coincident 1208 UTC NUCAPS profile... Read More
