The image above (from 2100 UTC on 28 February 2022) and below (from 0930 UTC on 1 March 2022) toggle between low-level estimates of 1000-mb dewpoint and GOES-16 IFR Probability fields. Is there a general relationship between the two? At first blush, it does seem like the IFR Probability fields... Read More
LightningCast (available here) is a CIMSS-developed product (created at the request of OPC and WPC) designed to relate current ABI fields (Band 2 (0.64 µm), 5 (1.61 µm), 13 (10.3 µm) and 15 (12.3 µm)) to the likelihood of future lightning. (A short training video on this product is available... Read More
Total Precipitable Water is a Level 2 Derived Product created from ABI (and ancillary) data (link to information on this product) The image above shows the product at 1900 UTC on 24 February 2022. It is immediately apparent that cloudy regions have no data! There are ways to fill in those gaps at different times... Read More
NUCAPS profiles from NOAA-20 provide a widespread swath of thermodynamic information that occurs (over CONUS) when normal radiosondes are not available (for example, around 1800 UTC as above). In addition, NUCAPS provides information in regions away from the sparse radiosonde network. The image above shows NUCAPS sounding availability points over... Read More
