“SnopViz“ is primarily a visualization tool for both observed snow profiles (CAAML V5.0 Snow Profile IACS) and simulation output of the snow-cover model SNOWPACK. The JavaScript application runs on any modern browser and does not require an active Internet connection. The latest release is available for download from models.slf.ch and examples can be run from snopviz.org. While the strength of this new visualization tool lies in its interactive features, a few of which are sketched below, it also provides means to output vector graphics files (SVG) or JSON object files for easy interfacing with other applications.
