The global N deposition grid dataset (2008-2020)

We compiled data from international N deposition networks and 1,390 published papers and constructed a Monitoring-based Global Nitrogen Deposition (MGND) database for 1977–2021, encompassing more than 50,000 site-years of data. Based on the cascading relationship of GDPpc → ENr → satellite N column concentration (CN, e.g., NH3 or NO2) → meteorological factors (e.g., mean annual precipitation, MAP) → FN, we developed a framework to generate a global N deposition grid dataset with a resolution of 0.125° × 0.125° for 2008–2020.
