Dynamic Land Ecosystem Model (DLEM) estimates of nitrogen inputs impact on global terrestrial major greenhouse gases (N2O, CO2, CH4) exchange and the transfer of nitrogen from land to water for the years 1970 and 2010

The dataset includes the effects of N inputs (N fertilizer, N deposition and manure N) on global terrestrial major greenhouse gases (N2O, CO2, CH4) exchange, nitrogen oxide-induced ozone impacts on global terrestrial carbon pools, and transfer of nitrogen from land to water in 1970 and 2010, which were estimated by the Dynamic Land Ecosystem Model (DLEM). These datasets are prepared for Chapter 11 and 13 for the upcoming International Nitrogen Assessment (INA) book.

Provenance & quality

Dynamic Land Ecosystem Model (DLEM) was used to assess the impacts of nitrogen inputs on GHG (N2O, CO2, CH4) exchange and the transfer of nitrogen from land to water. Gridded data sets used to drive DLEM simulations include climate, CO2 concentration and land use/cover change from NMIP (N2O Model Intercomparison Project), with IMAGE-GNM data on N fertilizer, N deposition and manure N from 1970 to 2010. MATLAB and ARCGIS were used to extract and process DLEM outputs.
