CRAS Forecast Imagery in AWIPS

Scott Lindstrom and Bob Aune

Other Contributors: Scott Bachmeier, Russ Dengel, Jordan Gerth, Steve Wanzong

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

Prerequisites

This is a basic course. There are no prerequisites.

Training Session Options

LMS students - to begin the training, use the web-based video or audio playback options below (if present for this session).

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. Certificates of completion for NOAA employees can be obtained on the E-Learning Management System LMS

   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

2. 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
