Meteorological Data

The meteorological data files contain measurements taken at 237 weather stations located throughout the United States for a period extending from 1961 to 1990. Exact collection dates vary by weather station. These data files are compatible with the EXAMS, PRZM, and EXPRESS systems distributed through the EPA Center for Exposure Assessment Modeling (CEAM).

A graphical index map is available to help find meteorological data for specific locations. Several Adobe Acrobat documents containing supplemental information about the weather stations and data collection are also available.
