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
