• LUMIP Coordination: Nicolas Vuichard
• LUMIP forced simulations:

Simul name	Tier	Coupled	Length (Y)	dependance	Information	Information2
deforest-glob	1	Y	80	after picontrol
land-hist	1	N	165+spinup (300)
land-hist-altStartYear	1	N	315
land-noLu	1	N	165	after spinup land-hist	Same as land-hist except no land-use change
land-hist-altLu1	2	N	165	after spinup land-hist	Same as land-hist except with two alternative land-use history reconstructions
land-hist-altLu2	2	N	165	after spinup land-hist	Same as land-hist except with two alternative land-use history reconstructions
land-cCO2	2	N	165	after spinup land-hist	Same as land-hist except with CO2 held constant
land-cClim	2	N	165	after spinup land-hist	Same as land-hist except with climate held constant
land-crop-grass	2	N	165	after spinup land-hist	Same as land-hist but with all new crop and pasture- land treated as unmanaged grassland
land-crop-noIrrigFert	2	N	165	after spinup land-hist	Same as land-hist except with plants in cropland area utilizing at least some form of crop management (e.g., planting and harvesting) rather than simulating crop- land vegetation as a natural grassland. . . Irrigated area and fertilizer area/use should be held constant.	Maintain 1850 irrigated area and fertilizer area/amount and without any additional crop man- agement except planting and harvesting. Irrigation amounts with irrigated area allowed to change.
land-crop-noIrrig	2	N	165	after spinup land-hist	"Same as land-hist but with irrigated area held at 1850 levels	only relevant if land-hist utilizes at least some form of crop management (e.g., planting and harvest- ing)"	Maintain 1850 irrigated area. Irrigation amounts within the 1850 irrigated area allowed to change
land-crop-noFert	2	N	165	after spinup land-hist	"Same as land-hist but with fertilization rates and area held at 1850 levels/distribution	only relevant if land- hist utilizes at least some form of crop management (e.g., planting and harvesting)"
land-noPasture	2	N	165	after spinup land-hist	"Same as land-hist but with grazing and other manage- ment on pastureland held at 1850 levels/distribution	i.e., all new pastureland is treated as unmanaged grass- land (as in land-crop-grass)."
land-noWoodHarv	2	N	165	after spinup land-hist	Same as land-hist but with wood harvest maintained at 1850 amounts/areas
land-noShiftcultivate	2	N	165	after spinup land-hist	Same as land-hist except shifting cultivation turned off. Only relevant for models where default model treats shifting cultivation (see Fig. 4)
land-noFire	2	N	165	after spinup land-hist	Same as land-hist but with anthropogenic ignition and suppression held to 1850 levels
hist-noLu	1	Y	164	picontrol	Same as concentration-driven CMIP6 historical (Tier 1) except with LULCC held constant.
ssp370- ssp126Lu	1	Y	85	after historical + preparation of ssp370	"Same as ScenarioMIP ssp370 (SSP3-7 deforestation scenario, Tier 1) except use land use from	ssp126 (SSP1-2.6 afforestation scenario)	concentration-driven."
ssp126- ssp370Lu	1	Y	85	after historical and preparation of ssp126	"Same as ScenarioMIP ssp126 (SSP1-2.6 afforestation scenario, Tier 1) except use land use from ssp370 (SSP3-7 deforestation scenario)	concentration-driven."
esm-ssp585- ssp126Lu	1	Y	85	after historical and preparation of esm-ssp585	"Same as C4MIP esm-ssp585 (Tier 1) except use SSP1-2.6 land use (af- forestation scenario)	emissions-driven"
