Summary

Atmospheric deposition of reactive nitrogen (Nr) due to human activities can have measurable effects on ecosystem processing and export of nutrients, groundwater and surface-water quality. Rates of Nr deposition to lower-elevation forests immediately adjacent to the Denver/Boulder urban area, however, have only recently been measured. The focus of this study was to determine the extent of urban and agricultural N pollution transport to the Colorado Front Range. In conjunction with the Network for Urban Atmospheric Nitrogen Chemistry (NUANC) and the National Atmospheric Deposition Program (NADP), we measured wet-plus-dry Nr deposition and evaluated spatial and seasonal variations in N deposition along an elevational gradient (1603 to [...]

Purpose

This data release contains nitrate and ammonium data collected from ion exchange resin columns (IERs) installed along an elevation and land cover gradient on the eastern slope of the Colorado Front Range. An objective of the study was to compare seasonal bulk atmospheric nitrogen deposition at sites along this gradient as well as to compare these results to those obtained by wet deposition samplers installed by the National Atmospheric Deposition Program (NADP). Results enabled an estimation of atmospheric nitrogen dry deposition.
