Integrated Model to Assess the Global Environment (IMAGE) Global Nutrient Model (GNM) simulations of past and future (2000-2100) nitrogen budgets and individual budget terms for agricultural and natural ecosystems

This dataset provides global and regional estimates of all components of nitrogen budgets in agricultural and natural ecosystems with a temporal resolution of five years that for the past and future period that goes from 2000 to 2100 at a 10 years interval. The last historical year is 2010.

The IMAGE-GNM model outputs were run for six different INMS scenarios:

The climate scenarios are represented as combination of SSP-RCP-N (shared socioeconomic pathways - representative concentration pathways - nitrogen pathways) :

1) Business as usual (SSP5-RCP8.5 Low N ambition)
2) Low N regulation (SSP2-RCP4.5 Low N ambition)
3) Medium N regulation (SSP2-RCP4.5 Moderate N ambition)
4) High N regulation (SSP2-RCP4.5 High N ambition)
5) Best Case (SSP1-RCP4.5 High N ambition)
6) Bioenergy (SSP1-RCP2.6 High N ambition with low meat & dairy diet)

This dataset has a spatial resolution of 0.5 x 0.5 degrees.
