NOAA-Unique Combined Atmospheric Processing System (NUCAPS) vertical profiles provide useful information derived from data from CrIS and ATMS instruments on board both Suomi-NPP and NOAA-20. Infrared Sounder information from CrIS gives profiles in clear/partly cloud regions, and ATMS supplies information in regions that are uniformly cloudy. (Click here for more... Read More
The animation above shows the 1721 UTC GOES-16 Visible (0.64 µm) image along with NUCAPS profile locations from a NOAA-20 overpass. Convection is approaching from the west, from central Wisconsin. NUCAPS soundings can give a good estimate for how far south that convective line might develop, and a north-south series... Read More
GOES-16 Visible Imagery, above (Click to animate), shows shower/thundershower development over eastern Oklahoma moving into Arkansas. At the end of the animation, 1946 UTC, NUCAPS Sounding profiles from 1926 UTC are shown, and they’re shown below too.The time 1946 UTC is about the earliest you could hope to have NUCAPS... Read More
Polar2Grid allows users to create true-color imagery from VIIRS (Visible Infrared Imaging Radiometer Suite) data from Suomi-NPP or NOAA-20. This tutorial will take you through the needed steps. Step one is to decide when you want the data; the ways to determine when a Polar Orbiter overflies a particular point... Read More
