Land procedure finidat = ' ' and CN procedure unclear

[m_a_a_rugenstein@uu_nl]

Hi all and Nan

we do attempt to run cesm1.0.3 in a deep time 1.9x2.5_gx1v6 configuration.

We crush at a point where finitdat (defined in run/lnd_in) is expected. But our finidat  is undefined = '' and the code in this case fills up the expected fields with Nan (and also -Nan).
Our run/lnd_in file looks like that:

&clm_inparm
co2_type                       = 'constant'
create_crop_landunit      = .false.
dtime                            = 1800
fatmgrid                        = '/home/heydtacc/models/cesm1_0_3/make_ACC_initial_files/created_paleo_files/lnd/griddata_0096x0144.nc'
fatmlndfrc                     = '/home/heydtacc/models/cesm1_0_3/make_ACC_initial_files/created_paleo_files/lnd/fracdata_0096x0144.nc'
finidat                           = ''
fpftcon                          = '/home/heydtacc/models/cesm1_0_3/inputdata/lnd/clm2/pftdata/pft-physiology.c110425.nc'
frivinp_rtm                    = '/home/heydtacc/models/cesm1_0_3/make_ACC_initial_files/created_paleo_files/lnd/rdirc_paleo_acc.0.5x0.5.nc'
fsnowaging                    = '/home/heydtacc/models/cesm1_0_3/inputdata/lnd/clm2/snicardata/snicar_drdt_bst_fit_60_c070416.nc'
fsnowoptics                   = '/home/heydtacc/models/cesm1_0_3/inputdata/lnd/clm2/snicardata/snicar_optics_5bnd_c090915.nc'
fsurdat                         = '/home/heydtacc/models/cesm1_0_3/make_ACC_initial_files/created_paleo_files/lnd/surfdata_0096x0144.nc'
ice_runoff                     = .true.
outnc_large_files           = .true.
rtm_nsteps                   = 6
urban_hac                    = 'ON_WASTEHEAT'
urban_traffic                 = .false.
/

in a modern case, which we use as standard the file looks like:
&clm_inparm
co2_ppmv                       = 367.0
co2_type                         = 'constant'
create_crop_landunit        = .false.
dtime                              = 1800
fatmgrid                          = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/griddata/griddata_1.9x2.5_060404.nc'
fatmlndfrc                       = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/griddata/fracdata_1.9x2.5_gx1v6_c090206.nc'
finidat                             = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/initdata/clmi.BCN.2000-01-01_1.9x2.5_gx1v6_simyr2000_c100309.nc'
fpftcon                           = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/pftdata/pft-physiology.c110425.nc'
frivinp_rtm                     = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/rtmdata/rdirc_0.5x0.5_simyr2000_c101124.nc'

fsnowoptics                    = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/snicardata/snicar_optics_5bnd_c090915.nc'
fsurdat                          = '/home/heydtacc/HUYGENS/modelcode/cesm1_0_3/inputdata/lnd/clm2/surfdata/surfdata_1.9x2.5_simyr2000_c091005.nc'
ice_runoff                      = .true.
outnc_large_files             = .true.
rtm_nsteps                     = 6
urban_hac                      = 'ON_WASTEHEAT'
urban_traffic                  = .false.

Thus, do we have to make up an equivalent of "clmi.BCN.2000-01-01_1.9x2.5_gx1v6_simyr2000_c100309.nc" for our case? Can we somehow regrid the standard one?


Also, for the CN recommended procedure, we do not understand
(a) what "B-case with high frequency compset" means.Can we use the B-case which we run to create the aerosols?
BAM_run_1.9x2.5_gx1v6 -compset B -res 1.9x2.5_gx1v6



(b) how/where do we actually use the output of these runs?


Thank you very much!
