The Theme Data section provides access to thousands of UMAC regional maps across the geosphere realms offered -- atmosphere, biosphere, hydrosphere, lithosphere, and androsphere. Maps include both historical averages and future projections based on data from a variety of sources. Each map is viewable in a preview size, a large format, and as a Google Earth layer. Monthly map series can also be viewed as year-long animations via Google Earth time series animation.

Select a map type from one of the Theme menus below right to start your browsing. For more detailed usage information, see the How To Use section.
