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.
