Training Materials for Forecasting Aviation Icing
A new CD-ROM, Forecasting Aviation Icing: The Icing Event of 6 March 1996 has been distributed to NWS offices. This CD-ROM contains a data set of 3300 images, graphics, text and derived products portraying an icing event that occurred over the continental United States on March 6, 1996. An application for viewing and exploring the data set is included.
This CD-ROM is a companion to several Web-based learning modules which COMET is developing as part of the Professional Development Series (PDS), Forecasting Aviation Icing. See the Web site http://www.meted.ucar.edu/icing/. This hybrid approach of combining CD-ROM data with Web-based modules takes advantage of the strengths of both technologies. With Web-based lessons, students can access up-to-date training materials on the Internet, while the CD-ROMs allow them to browse and display thousands of data products without the delays imposed by slow Internet connections.
The first Web module that will utilize this CD is Icing Assessment Using Soundings and Wind Profiles, part of the Professional Competency Unit #6: Determining Icing Type and Severity (refer to the meted Web site). Portions of the Professional Competency Unit #6 are excerpted below ("W" indicates Web-based training).
Icing Assessment and Forecast Tools: A series of short Web-based lessons that demonstrate the use of various diagnostic tools to evaluate the mesoscale atmospheric parameters pertinent to icing type and severity. These lessons expand upon concepts and methods introduced in the first Web-based module (W6.1) by providing in-depth demonstration and intensive practice.
Icing Assessment Using Soundings and Wind Profiles: This Web-based lesson demonstrates patterns and methods for identifying temperature and wind profiles favorable for icing. Includes numerous practice exercises allowing learners to improve their skills in icing assessment using these basic observational tools.
Icing Assessment with Observations and Pilot Reports: Demonstrates patterns and methods for identifying icing threats using surface and upper-air observations and PIREPs. Includes numerous practice exercises allowing learners to improve their skills in icing assessment using these basic observational tools.
Icing Assessment with Satellite Imagery: Demonstrates patterns and methods for identifying icing threats using visible and infrared (3.9, 6.7, 10.7 micron) imagery and derived products. Includes practice exercises allowing learners to improve their familiarity and skill with satellite data analysis. Part of the content to be presented in this instructional component are provided in the multimedia CD-ROM M6.3, GOES IR Imagery Including Winter and Icing Applications.
Icing Assessment with Radar Imagery: Demonstrates patterns and methods for identifying bright bands and other icing signatures using both local radar and national mosaic imagery and derived products. Includes practice exercises allowing learners to improve their familiarity and skill with radar data analysis.
This CD-ROM application runs under Windows 95 or 98 and requires either Netscape 4.0+ or Internet Explorer 4.03+. The CD will not run properly using the 3.0 versions of either browser. It is recommended that the latest version of either browser be installed prior to installation of the CD. Following directions from the Help link on the meted Web site, you can easily download the latest versions.
COMET welcomes comments users may have regarding the content, instructional approach, or use of this Web module.

Also under the Forecasting Aviation Icing PDS, PCU #6: Determining Icing Type and Severity, a second CD-ROM module has been distributed. GOES IR Imagery Including Winter and Icing Applications contains a mini-case study in which 3.9 micron imagery is applied to forecasting a major icing outbreak over the midwestern U.S. This case also covers how to use the conventional infrared and visible imagery in a potential icing situation. There are two other winter storm case studies which emphasize satellite imagery. The rest of the module contains basic background information on all of the spectral channels.
This module is appropriate both as review of remote sensing concepts and the GOES 10.7 and 10.9 imager channels, as well as an example of how to use GOES imager data to forecast icing and snowfall events. This module also requires Windows 95 or Windows 98 and either the Netscape 4.0+ or Internet 4.03+ browser versions, however, all module materials are contained on the CD-ROM and there is no need to be connected to the Internet. Feedback on this module should be directed to either:
