From the editor

A new umbrella Web site for UCAR, NCAR, and UOP provides enhanced content in a colorful, easy-to-navigate format. Hundreds of new pages have been created for the site. A Research Tools section takes you directly to the most-requested data sets, applications, and other community resources. Lay people can learn more about our work at News Center and Our Research.

Hundreds of high-quality digital images are now available to the community through UCAR's new Digital image Library. Users can browse by category or search by keyword. High-resolution files can be downloaded on the spot, and there is no fee for use in noncommercial activities.
