v15 v16 13 13 The protocol comprises: 14 14 - '''1) A long spin up simulation''' equivalent to several thousands of years should be done, recycling the meteorological forcing (usually cycling over the first 10 years of available forcing files) and choosing the atmospheric CO2 concentration of pre-industrial conditions. This brings the above and below ground C pools into equilibrium. It should be done either with: 15 - The iterative pseudo-analytical spinup procedure : in this case a relatively shorter simulation should first be done (around 200 to 300 years) in order to bring the above ground C pools and fluxes into equilibrium. This provides an equilibrium for the input of C to the soil; the iterative pseudo-analytical spinup configuration then allows to bring the soil carbon pools to equilibrium in a few matrix inversions, given that the soil carbon dynamic follows first order kinetic equations.15 - The iterative pseudo-analytical spinup procedure (see below): in this case a relatively shorter simulation should first be done (around 200 to 300 years) in order to bring the above ground C pools and fluxes into equilibrium.
