This data release provides estimates of monthly wet atmospheric deposition of total inorganic nitrogen (TIN)--the summation of nitrate (NO3) and ammonium (NH4) ions--for the conterminous United States from 1999 through 2020 in units of kilograms nitrogen per square kilometer per month with spatial reference ESPG 4326. The spatial resolution of the gridded data provided in this release is approximately 5 km. The source data used to provide wet deposition estimates include monthly atmospheric concentration data interpolated between National Atmospheric Deposition Program (NADP, 2022) observation stations and monthly precipitation estimates from the National Oceanic and Atmospheric Administration's ClimGrid data (NOAA, 2022). See process steps for details.
