Introduction


The objective of this session is to better understand and utilize techniques for the detection and analysis of fog and low clouds using data from GOES and other satellites. The lesson will emphasize nighttime detection by means of a bi-spectral (11-3.9 mm) IR image product, but will also address daytime techniques using visible, near-Infrared, and shortwave IR channels. Experimental products such as fog depth and low cloud base height will be discussed, along with additional satellite products useful in the prediction of fog formation.

Training Session Options


  1. VISITview playback without Audio – You may step through the VISITview file on your own to view the presentation. If talking points are available, you may use these in tandem with going through the slides.

    Create a directory to download the playback file from the following site: http://rammb.cira.colostate.edu/training/visit/training_sessions/fog_detection_and_analysis_with_satellite_data/fog_detection_and_analysis_with_satellite_data.exe

    After extracting the files into that directory click on the visitlocal.bat file to start the lesson. Advance slides on your own using the navigation controls (i.e., the Next button will advance to the next slide)
