Regional and Mesoscale Meteorology Branch

Introduction:

Objectives: Identify and track low-level moisture utilizing GOES imagery with other datasets.

• Nighttime detection:
  • 10.7 um imagery
  • Fog product
• Daytime detection using:
  • Visible imagery
  • 10.7 um imagery
• Cloudy or clear conditions

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 (53 MB) from the following link: http://rammb.cira.colostate.edu/training/visit/training_sessions/monitoring_gulf_moisture_return/monitoring_gulf_moisture_return_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:
