SASSI... Situational Awareness for Severe Storms Intercept
SASSI is an application for combining Geographical Information System (GIS), weather information including mobile platform data, and customized chat. The application is specifically designed to facilitate the coordination and effectiveness of field teams participating in mobile mesoscale weather experiments. More...
The 2010 Version of SASSI is the final version developed under NSF support. Any further development will be solely supported by Rasmussen Systems and will not be in the public domain unless the the clients supporting the development require it to be so. More information, and a source code tarball, is available on the page describing SASSI 2010.

Particle Analysis
Rasmussen Systems has produced an IDL software application to analyze particle images produced by a videosonde developed at the National Severe Storms Laboratory (NSSL). The application combines the particle images with sounding data, and allows the user to select a set of images for analysis. Image processing techniques are used to determine particle locations, sizes, shape, and orientation. Summary statistics are provided in a variety of output formats.
Particle Analysis tool display. Upper portion shows identified particles and their fitted shape and size. Lower left is a graph of sounding parameters, with selection tools allowing the user to choose a subset of images for statistical analysis. The lower right is a histogram of particle sizes for the selected subset.
