Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. Many of these sets found their way to colleges and universities around the United States. The University of Wisconsin's Department of Atmospheric and Oceanic Sciences donated their collection to the Schwerdtfeger Library in 2000. Shortly after, the ... Full description.

This site is all about snow crystals and snowflakes. The many facets of snow crystals are described here, along with attempts to understand their formation. This site includes collections of super-high-resolution snow crystal photos, as well as links to learn about snow crystal classifications and how to make snow crystal fossils. Included in the study of how snow crystals form, these researchers ... Full description.

The Global Climate Animations site contains animations of the Earth's climate system for educational and research purposes. The animations show the climatology of the seasonal cycle for selected climate variables for the time period 1959-1997, based on data from the NCEP/NCAR 40-Year Reanalysis Project. The individual frames in each animation show the map pattern of the long-term monthly averages ... Full description.
