Hi all, For some air quality calculations, I'd like to output the bottom 2 layers of a few fields. Starting with temperature and O3, I can get the surface temperature with 'TS' and the the surface O3 concentration with 'O3_SRF'. Is there a way to get just the bottom 2 layers of the atmosphere...

Hi all, Quick and hopefully easy question. I'm looking for a CAM6 output field which will give me cloud droplet number concentration on pressure levels (i.e. a 3D version of CDNUMC) for some offline calculations. I think I might want AWNC ('Average cloud water number conc') or ICWNC ('Prognostic...

Hello, all of you. I am running a port with atmospheric CAM only in the CESM 2.2.0. I am getting an error after many warnings: "Warning: incorrect ice nucleation number (nuci reset =0)". How could I resolve this error?

HI, I'm getting the following reproducible error in CAM while running a CAM6 f09 FHIST case with cam_cesm2_2_rel_03 (I think). Oddly it is able to run over 10 years before this error. The modifications I make are 1) using coupled CESM2 SSTs and sea ice rather than observed and 2) masking out the...

Hi all, I have a user-defined CESM2.2.0 compset on Cheyenne which runs fine. However, after changing the initial condition files used, it fails to run beyond the first timestep with the following error in cesm.log: ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_z...

Hi all, I'm running a coupled atmosphere-ocean compset in CESM2.2.0 on Cheyenne. I have successfully run this compset for 10 years - in the next run of 10 years it crashed at year 18. The error in the cesm.log is: WHL, oc_tavg_helper is already associated; reset the tavg fields 0: sysmem...

Hi all, I am new to CAM and am confused about the meaning of various cloud fraction outputs. I am running a simulation with the BSSP585 compset using CESM2.1.3. The macrop_scheme and shallow_scheme ='CLUBB_SGS', the deep_scheme='ZM',and the microp_scheme ='MG'. My first question is: what is...

Hello all, I am doing a bias correction for SST & Ice_cov data. I want a fully coupled model produced (BHIST) sst & ice_cov data from 1850-2014. Kindly provide me with the data. Thanking you. With regards, Sushovan Ghosh

Hi all, I'm trying to build a transient run based on an existing non-transient run I made previously. The problem I am having is trying to turn off 'ext_frc_cycle_yr', 'srf_emis_cycle_yr', etc. The model doesn't run because these values are fixed at 2010, even though I have not set them in...

Hi all, I have a CESM2.2.0 run on Cheyenne which crashes after submitting, but I can't see an obvious error source. It's a land-atmosphere only run based on the FC2010climo compset. The error message in the cesm log is the usual: 0:MCT::m_Router::initp_: GSMap indices not increasing...Will...

Greetings, We are trying to make some code modification in some modules in CAM6.3 in order to customize some cases we want to run. The reason we are doing that it is because we need to specify some inputs which are not available as CESM has been built. Therefore, we found that if we want to...

Hi all, We are trying to have new outputs in our CESM2.2 run simulations and we found an old reference for CAM 3.0: Adding New Output Variables Nevertheless, when we look at the same modules (history.F90) suggested in previous link, we do not find the functions such as: addfld and outfld...

Hi all, We are trying to run a short case using CESM2.2 in order to understand how to customize future simulations. Our case is something like this: ./create_newcase --case cam60f2000_2days --compset F2000climo --res f09_f09_mg17 cd cam60f2000_2days ./case.setup Then we want to modify the...

I am trying to perform a simple Held-Suarez configuration in CAM, with AOA tracers active. I first spun up the model with a period of 1.5 years without including -age_of_air_trcs to CAM_CONFIG_OPTS I am then trying to do a longer run using this spun up state as the initial condition. For this...

Hi all, I am running CESM2 in a CAM-chem configuration for the year 2050. I have set all surface emissions, lateral boundary conditions, and external forcing specifiers to 2050. However, I am having a problem setting the continuous volcanic emissions. I am aware that these are time averages of...

Hi all, I would like to interpolate some initial conditions from WACCM (70 vertical levels) to use in a CAM-chem run (32 vertical levels) using the interpic tool. I can see that a 32-level case is non-standard in the script 'create_template.ncl' which is required to run interpic. Sure enough...

Hi all, I'm trying to use interpic to generate initial conditions for CAM. However, I am unable to build the executable. The following error appears when I run gmake: pgf90 -c -I/usr/local/include -fast control.f90 gmake: pgf90: Command not found Makefile:106: recipe for target 'control.o'...

Dear All, I'm trying to run a set of experiments using the Eulerian dycore in aquaplanet mode. The model can build the case successfully, and it executes until initialization is complete, after which it throws the error. ERROR: TPHYSAC error: grid contains non-ocean point I have attached all...

Hello everyone, I am trying to run a set of experiments with the eulerian dynamical core and T85_T85 resolution in CESM v2.1.3. I was able to create the case using the following command: ./create_newcase --case /mnt/lustre/cas2/casabu/Abu/cesm21/cases/test1 --compset...

Hi, I tried to run a case with compset of F2000climo (Is it similar to F2000 in CESM 1.2.2?) and the resolution of f09_g16. The partial error message of cesm.log is as follow (The whole file is also attached): I just create case then setup, build and run, have not modified any config files yet...
