This is a basic teletraining module to describe the flow of CRAS forecast imagery into AWIPS. Topics covered include:
- CRAS Model description:
- Satellite information used
- Horizontal Dissipation effects
- 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
- 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
- Live VISIT teletraining (with an instructor leading the session). Check the VISIT Training Calendar to signup for teletraining. The session will last 45 minutes. This teletraining session uses the VISITview software, where a Windows PC with an Internet connection is needed.Please follow the teletraining installation instructions to install the session
- Talking points are available for this lesson and may be printed out to easily review the session in detail at any time.
