Regional and Mesoscale Meteorology Branch

Introduction:

This is the third in a series of VISIT teletraining sessions on GOES Rapid Scan Operations (RSO) Imagery. The first session is titled Using GOES Rapid Scan Operations (RSO) Imagery in AWIPS and concentrated on what RSO is and how to call it. The second session is titled Mesoanalysis of convective weather using GOES RSO imagery and concentrated on incorporating satellite data in the short-range forecast, nowcasting, and warning decision making processes.

The teletraining session consists of two parts. Both parts must be completed to get a certificate of completion as there are different points made in each part. Both parts 1 and 2 are contained in the same file. Each part takes about 75 minutes to complete. The Web-based video / audio playback versions take about 130 minutes.

Objectives:

1. To review principles of using RSO to:
   • Identify different air masses
   • Analyze storm scale features
2. To demonstrate how RSO imagery is used most effectively with other datasets such as lightning, radar etc.
3. To present advanced case studies:
   • Severe weather cases that encompass a variety of regions across the CONUS
   • Application on multiple scales

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 Learning 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 (231 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/rso_3/rso_3_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. YouTube video:
