    66The carbon stocks and fluxes take a relatively long time to be in equilibrium when starting from zero. 
    77 - Vegetation C stocks/fluxes: The spinup needs to bring the vegetation above and below ground carbon stocks at equilibrium. This is relatively short for the LAI: few decades or even just one decade are enough. For the other C pools it is linked to the turnover of the !Sap/Heart/wood C pools: usually 100 to 200 years are sufficient.   
    8  - Soil C stocks/fluxes: These pools take a much longer time to be in equilibrium as the passive C pool has a turnover on the order of one thousand years. Usually we need several thousand years to reach the equilibrium. Using the in-built iterative pseudo-analytical spinup procedure reduces this step as we then only need to have the input of C to the soil in equilibrium.
