Detecting Low-level Thunderstorm Outflow Boundaries At Night Using GOES
Based on “Nighttime Detection of Low-level Thunderstorm Outflow Using a GOES Multispectral Image Product” by J. Dostalek et al
This case reviews the use of the GOES imager channels to detect and monitor the evolution of LTO boundaries at night. LTO boundaries have been monitored for years using the high resolution visible channel during the day. With the advent of the 3.9 micron channel on the GOES-8, -9 and –10 imager instrument, it is now possible to use the fog/stratus product to monitor the LTO boundaries during the night.
The goal of this teletraining session is to review the use of the various GOES IR channels and products in monitoring LTO boundaries at night.
Training Session Options
- 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/lto_boundaries_at_night/lto_boundaries_at_night.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)
- Talking points are available for this lesson and may be printed out to easily review the session in detail at any time.
