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...

The stable hydrogen (delta 2H) and oxygen (delta 18O) isotopic compositions of more than 4,300 weekly composite samples of precipitation from thirteen National Atmospheric Deposition Program (NADP) sites (CO02, CO08, CO09, CO10, CO21, CO89, CO91, CO92, CO93, CO96, CO97, CO98, and UT09) in Colorado and Utah were analyzed on archived samples obtained from NADP over various time periods between January 2001 and October 2022. The samples are from the NADP National Trends Network (NTN) with weekly sample frequency. Data on site location, collection begin and end dates, sample volume and precipitation amounts were furnished from publicly-available NADP sources and were not evaluated for accuracy. Measured values range...

The stable hydrogen (delta 2H) and oxygen (delta 18O) isotopic compositions of more than 6,400 daily or weekly composite samples of precipitation from nine National Atmospheric Deposition Program (NADP) sites (DE02, MD07, NJ99, NY67, NY68, PA00, PA15, PA72, and PA98) in New York, New Jersey, Delaware, Maryland and Pennsylvania were analyzed on archived samples obtained from NADP over various time periods from as early as 1992. The samples are from the NADP National Trends Network (NTN) with weekly sample frequency, and the former NADP AIRMoN network, sampled daily within 24 hours of start of precipitation. Data on site location, collection begin and end dates, sample volume and precipitation amounts were furnished...
