Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: National Atmospheric Deposition Program (NADP) National Trends Network (NTN) 1985-2014 This data set represents National Atmospheric Deposition Program (NADP) National Trends Network average of annual precipitation-weighted mean atmospheric deposition for seven select constituents from years 1985-2014 compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The seven constiuents presented here are: Calcium, Nitrate, Sulfate, Inorganic Nitrogen, Magnesium, Ammonium, and Chloride. Units are kilograms per hectare. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data was produced by...
