Weather

wuarchive.wustl.edu The `/multimedia/images/wx' directory contains GIF weather images of North America. Files are updated hourly and take this general form: `CV100222'. The first two letters tell the type of file: CV means it is a visible-light photo taken by a weather satellite. CI images are similar, but use infrared light. Both these are in black and white. Files that begin with SA are color radar maps of the U.S. that show severe weather patterns but also fronts and temperatures in major cities. The numbers indicate the date and time (in GMT - five hours ahead of EST) of the image: the first two numbers represent the month, the next two the date, the last two the hour. The file `WXKEY.GIF' explains the various symbols in SA files.
