Marcia Politovich of the NCAR Research Applications Program (RAP) is the principle subject matter expert for this
Web-based learning module. The module teaches how to assess vertical profiles of wind, temperature, dewpoint, and frost point in order to diagnose airmass characteristics, cloud layers, and possible aviation icing layers. Topics include strengths, weaknesses, and appropriate uses of rawinsonde and profiler data for assessment of aviation icing, icing characteristics of the different extratropical cyclone air masses, identification of dry and saturated layers and possible zones of favorable conditions for aircraft icing, and ice seeding and glaciation processes. If you wish, you may launch the module from this location. Note: This module requires use of the companion CD-ROM called The Icing Event of 6 March 1996.
