The hourly data used in building these daily summaries are obtained from the USAF Climatology Center, located in the Federal Climate Complex w ith NCDC.

The latest week of the daily summary data is placed on line by NCDC for easy access and download by outside users, and is normally available about 4 days after the end of the data week. The on line data files begin with January 1994. About 8000 stations' data are typically included in the dataset.

They are accessible through our WWW server (ncdc.noaa.gov/) or through direct ftp connection. Other periods of the summary of day data (up to 20 years or more) can be obtained off-line from NCDC. Also, the data can be displayed in graphical form using the v isualization software on our WWW server.

This allows the user to select the country and station(s) of interest, and quickly display the element(s) chosen. The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
