VAWS: Recent Advances in Water Vapor Products from Satellites for Forecasters

Speaker: John Forsythe

Forecasters routinely monitor total precipitable water (TPW) in the atmosphere via the NOAA operational blended TPW product. A new Advected Layer Precipitable Water (ALPW) product provides a vertical dimension and depicts long-fetch flows of moisture which enhance flood events. How these products are generated will be explained, and typical forecast uses including in the Alaska region will be presented. Upcoming improvements to these products will be discussed.
