Title

Land-Use Harmonization (LUH2)

Description

This is currently a placeholder for this dataset, as it contains a number of projected scenarios for land use. This dataset is used in CMIP6 to capture land-use changes. It is split into a few distinct files that represent various scenarios, and I am not sure yet which ones should be ingested. Either way, they are fairly small so perhaps ingesting all is the way to go.

Spatial resolution: 0.25 degree Temporal resolution: annual Units: fraction of land use type within a grid cell

The data are fractions of a land-use type per grid cell. Here are the classes:

Variable Name | Units | Description | Data Type -- | -- | -- | -- primf | fraction of grid cell | forested primary land | states, transitions primn | fraction of grid cell | non-forested primary land | states, transitions pastr | fraction of grid cell | managed pasture | states, transitions range | fraction of grid cell | rangeland | states, transitions urban | fraction of grid cell | urban land | states, transitions c3ann | fraction of grid cell | C3 annual crops | states, transitions, management c3per | fraction of grid cell | C3 perennial crops | states, transitions, management c4ann | fraction of grid cell | C4 annual crops | states, transitions, management c4per | fraction of grid cell | C4 perennial crops | states, transitions, management c3nfx | fraction of grid cell | C3 nitrogen-fixing crops | states, transitions, management secdf | fraction of grid cell | potentially forested secondary land | states, transitions secdn | fraction of grid cell | potentially non-forested secondary land | states, transitions secma | years | secondary mean age | states secmb | kg C/m^2 | secondary mean biomass density | states
