Description:

Abstract:

The nitrogen deposition dataset contains values, in pounds per acre, of total annual nitrogen deposition for each of the NADP collection sites across the southern U.S. The sulfate deposition dataset contains values, in pounds per acre, of total annual sulfate deposition for each of the NADP collection sites across the southern U.S.

Purpose:

The data were developed by NADP and the National Trends Network to monitor long-term, geographical trends in the chemistry of precipitation.
