Outputs from the Land Model

Description of Outputs

Name Resolution Unit Query XML Tag
Land use and land cover By GLU, land leaf, and year thousand \(km^2\) or 1 land-allocation
Land use change emissions By GLU and land leaf MtC / year land-use-change-emission
Change in above ground carbon By GLU and land leaf MtC / year   above-land-use-change-emission
Change in below ground carbon By GLU and land leaf MtC / year   below-land-use-change-emission
Above ground carbon stock By GLU and land leaf MtC above-ground-carbon-stock
Profit rate By GLU and land leaf 1975$/thous km2 profit-rate


Outputs are specified in the startVisitLandLeaf and startVisitCarbonCalc methods of xml_db_outputter.cpp.

1: There is a long list of standard queries that report land allocation outputs. The "detailed land allocation" query will list land for every single land leaf and region combo (see land nesting for a complete list of land leafs). The "aggregated land allocation" query listed above will aggregate land into 12 categories (e.g., crops, biomass, etc.). There are also queries that will return land allocation for an individual GLU ("land allocation in a specified land use region") or total land by crop ("land allocation by land crop").
