dear CLM forum,
we are doing an I1850CN spinup with CLM4.0 in order to produce the
initial condition for the CESM1.1.2 simulation that we will perform
at CMCC; with respect to the common implementation we are using a
finite volume grid at 1 degree (f09) with slightly different land-sea
mask in order to be consistent with the NEMO model that we adopt
for the ocean circulation
we are attaching the relevant summary plots for the total carbon
and nitrogen in the accelerated run (AD spinup) and the final
spinup (without acceleration)
we noted that even though the accelerated run seems to be close
to the equilibrium, the final spinup, that we performed after
about 850, 1000, 1250 and 2250 years of acceleration are not
in equilibrium and they show an almost constant trend during
the 50 years of simulations
is there an explanation for that? what can we do to check if we
are doing right, or to fix the problem?
thanks in advance,cheers,
