Output for regional/singlepoint simulations

[swieneke@meteo_uni-koeln_de]

Hello everyone,

I created a 1PT_1PT ICN Case with CESM1.0.4 to simulate NEE/GPP/NPP. I used interpinic to create a Spinup restart file and configured the user_nl_clm accordingly. The simulation run through but unfortunately i didnt get a NEE/GPP/NPP output. When i configure the user_nl_clm file to exclude all data and include NEE the model crashed with the error:

 htapes_fieldlist ERROR: NEE in fincl(            1 ) for history tape
            1  not found

In the error message is a MASTER FIELD LIST where all posible Output variables are listed, and there is no parameter for NEE/GPP/NPP. When I run a global Case everything works fine. Is it not possible to get CO2 fluxes from PT1_PT1 simulations? Or am I unable to get NEE/GPP/NPP because of the Spinupfile?

Cheers Sebastian

The only variable (regarding CO2 fluxes) which can be added in the pt1_pt1 simulations is the biogenic co2 flux (BIOGENCO) history field. But this is the the BVOC flux right?

Ok now I moved the NEE hist_addfld1d in the histFldsMod.F90 from the

!-------------------------------
! C flux variables - native to column
!-------------------------------
! add history fields for all CLAMP CN variables

part to the canopy part and fortunately get a NEE history field. But unfortunately it is empty. I guess that this Problem is related to the pt1_pt1 simulation. Is it possible that NEE is not calculated in regional and singlepoint simulations? Can I change this easily or is this a bigger task?

Cheers Sebastian

Hi, Sebastian

I think that the model can not output NEE/GPP if the CN model is closed. Please check if your case opened the CN model.

I looked over my configuration again and saw that i overwrote my ./xmlchange -file env_conf.xml -id CLM_CONFIG_OPTS -val "-bgc cn" option. So you were right, the CN Model wasnt active. Thanks for that tip.

Cheers Sebastian
