Tracking the Elevated Mixed Layer with a new GOES-R Water Vapor Band

Dan Bikos, Ed Szoke, and Dan Lindsey


This training session describes a technique to track the elevated mixed layer (EML) that can be an important ingredient for severe thunderstorm events. Currently, a blend of soundings and GOES sounder 7.4 um band is utilized, however with GOES-R the 7.34 um band will be available at much higher spatial and temporal resolution, making this technique much more efficient to apply.


This is a basic course. There are no prerequisites. For those interested in additional background information, see the VISIT session titled Water Vapor Imagery Analysis for Severe Weather
