Resolution
Spatial aggregation: regular grid
Horizontal resolution: 0.5°x0.5°
Additional spatial aggregation & resolution information: ORCHIDEE will be run at the resolution of 1o*1o, while we will provide interpolated 0.5o*0.5o output
Temporal resolution of input data: climate variables: daily
Temporal resolution of input data: co2: annual
Temporal resolution of input data: land use/land cover: annual
Temporal resolution of input data: soil: constant
Input data
Additional input data sets: STN-30p river network https://daac.ornl.gov/ISLSCP_II/guides/river_routing_stn_xdeg.html
Climate variables: tasmax, tasmin, rlds, rsds, ps, pr
Spin-up
Was a spin-up performed?: Yes
Spin-up design: We use the 1801-1820 climate condition, pre-industry CO2 (287.14 ppm), land cover map of 1860 to do the spin-up until the soil carbon to be equilibrium. Then a simulation of 1801-1860 pre-industrial period will be run. All other runs since 1861 will follow the protocol, and will be started from previous 1801-1860 run.
Natural Vegetation
Natural vegetation partition: Dynamic natural vegetation cover, with prescribed crop and pasture area.
Natural vegetation dynamics: DGVM
Management & Adaptation Measures
Management: no
Technological Progress
Technological progress: No
Soil
Soil layers: 11 layer water difussion
Water Use
Water-use types: No
Water-use sectors: we only have nosoc runs
Routing
Runoff routing: STN-30p river network
Land Use
Land-use change effects: MIRCA dynamic land use change
Dams & Reservoirs
Dam and reservoir implementation: No
Calibration
Was the model calibrated?: No
Vegetation
Is co2 fertilisation accounted for?: Yes
How is vegetation represented?: Dynamic natural vegetation cover, with prescribed crop and pasture area.
Methods
Potential evapotranspiration: "Penman-Monteith, Milly’s correction for soil moisture stress is applied."
Snow melt: Energy balance at the snow surface
