Important note: all files available here for downloading have been
"compressed" under Unix in order to save space. A single compressed file
has ".Z" extension. You may need to respecify the ".Z" extension when you save
a compressed file. Some of our archives also have multiple files (such as
time series) that are "tar"ed under Unix and have a ".tar" extension. As a
result, files must be "untared" and/or "uncompressed" to return them to
their original ASCII format, before they may be used.
How to cite our data: we recommend that users cite pertinent information contained in the README files associated with the data sets. A citation should contain the creators' (our) names and the creation and/or most-recent-modification date, as well as the title and URL associated with the data set. An example of how to cite one of our data sets is: Willmott, C. J. and K. Matsuura (2001) Terrestrial Air Temperature and Precipitation: Monthly and Annual Time Series (1950 - 1999), http://climate.geog.udel.edu/~climate/html_pages/README.ghcn_ts2.html.
