9.9. Variables that have a value for each soil biogeochemistry pool at each soil biogeochemistry layer at each land gridpoint

With the single-pool soil model (soil_bgc_model = 1) there is a single soil carbon pool and a single layer.

If the RothC or ECOSSE models are chosen (soil_bgc_model = 2 or 3) there are 4 soil carbon pools (decomposable plant material, resistant plant material, biomass, humus) for each soil layer.

For RothC, if l_layeredc = TRUE there are sm_levels soil layers (with 4 pools for each), otherwise a single bulk soil layer is used.

For ECOSSE the number of soil layers is dim_cslayer.
