TOWR-S RPM v22 Feature: Gridded NUCAPS 

April 6, 2022

 

Q. What is new with Gridded NUCAPS?
A: There are three adjustments to the Gridded NUCAPS products in AWIPS with TOWR-S RPM version 22.

  • Precipitable water is now displayed in units of inches, rather than centimeters.
  • 2 Meter Temperature is now in degrees Fahrenheit, rather than Kelvin.
  • The Haines Index is now available in 3 layers, rather than 1. The layers are categorized by pressure level - Low (950-850 mb), Middle (850-700 mb), and High (700-500 mb).

 

More information about the JPSS NUCAPS data can be found in this TOWR-S Dataset Guide, and in this Quick Guide.
