This teletraining session was updated in May 2008, and replaces the previous QuikSCAT Winds session. New material includes displaying and interpreting high resolution QuikSCAT data in AWIPS OB 8.3, and expanded extratropical cyclone applications.

Learning Objectives:


• Understand how QuikSCAT works



• Become aware of the data limitations



• Know how the 12.5 km high-resolution data is presented in AWIPS



• Understand how to apply QuikSCAT data operationally by examining several examples

This is a basic course.

There are no prerequisites.

A.) The interactive VISITview teletraining session. (To be used with a VISIT instructor leading the session ). Click here to signup for teletraining. The session will last 60 minutes. This teletraining session uses the VISITview software, where Windows PC with an Internet connection is needed.

B.) Web-based Video training session

C.) VISITview Audio playback - This VISITview file contains recorded audio and annotations and can be taken at anytime. Certificates of completion for NOAA employees can be obtained through your Science Operation Officer or training point of contact. For detailed information on how to view the recorded session click here.

Create a directory to download the audio playback file (it is about 70 MB in size) from one of the following sites:

You may either request a DVD (with all VISIT audio playback files) OR download the file (see instructions below):

ftp://rammftp.cira.colostate.edu/bikos/audio/Qscat_audio_version_final.exe
OR
ftp://ftp.ssec.wisc.edu/visit/audio/Qscat_audio_version_final.exe

After extracting the files into that directory click on the visitauto.bat file to start the lesson.
