Introduction


This is a basic teletraining module to describe the flow of CRAS forecast imagery into AWIPS. Topics covered include:

  • CRAS Model description:
    1. Satellite information used
    2. Horizontal Dissipation effects
    3. Initialization
  • Data flow from CRAS to AWIPS
  • Window Channel and water vapor model imagery

Training Session Options


NOAA/NWS students – to begin the training, use the web-based video, YouTube video, or audio playback options below (if present for this session). Certificates of completion for NOAA/NWS employees can be obtained by accessing the session via the Commerce Learn Center

  1. Audio playback (recommended for low-bandwidth users) – This is an audio playback version in the form of a downloadable VISITview and can be taken at anytime.

    Create a directory to download the audio playback file (114 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/cras_forecast_imagery_in_awips/cras_forecast_imagery_in_awips_audio.exe

    After extracting the files into that directory click on either the visitplay.bat or visitauto.bat file to start the lesson. If both files are present, use visitauto.bat
