Hi everyone, I was trying to run a PETM simulation using the dt2.0_cesm1_2_2_1 following the paleoToolkit documentation. I have completed steps 1 to 31 outlined in the Setup Recipe. However, when I attempt to run a fully coupled simulation with compset BPETMC5CN and resolution f19_g16, I...

Dear CESM Community, I am currently working on an aquaplanet simulation using CESM, and I would like to disable specific land-based aerosol modes while using MAM7. The aerosol modes I want to remove are as follows: Primary carbon Fine dust Coarse dust However, I still want to keep sea salt...

Hi, I'm trying to interpret my cam initial condition from f09_f09 to f02_f02. I successfully make the executable interpic_new in cam tools. And also add the vertical layers to my template file as following cp fv_0.23x0.31.nc fv_0.23x0.31_L32.nc ncks -vhyai,hyam,hybi,hybm...

Hello. I am looking for ocean and atmosphere output variables for the CESM1-CAM5 piControl simulation for comparison with a paleoclimate simulation. I have searched through ESGF nodes and NCAR climate data gateway. I did manage to find data on the ESGF CMIP5 output, but the download for many...

Hi everyone, I am running CAM4 on CESM2.1.3, but would like to have a better Aerosol-Cloud Interaction. I therefore tried to change the microphysics package to the one developed for CESM5, by running: ./xmlchange --append CAM_CONFIG_OPTS='-microphys mg1'. I can build the case, however when...

I have build a default cam with compset (F_1850-PDAY_CAM5) with default SST and SIC. I have started the model from 1950. It run till 1953-09-07 and after this date model crashed. Please find the last few lines of error in cesm.log file mentioned below. Please see the README.case file to know the...

Hello, I'm trying to run a simple pre-industrial control test case with CESM1.2.2 and CAM5 with COSP enabled but I'm running into an error at the build step. For reference, I have no problems running B-compsets with CAM4 and COSP on my machine, this build error only arises when I use CAM5...

I have recently been looking at the paper Climate variability and change since 850 CE (Climate Variability and Change since 850 CE: An Ensemble Approach with the Community Earth System Model) and the corresponding data sets that go with it at www2.cesm.ucar.edu/models/experiments/LME. What I...

Running SCAM for IOP cases in CAM5 successfully with the option "-dyn eul". Can we include nudging for SCAM IOP apart from the forcing with "iopfile". For this included the below and tried different options "-dyn fv -offline_dyn" and not successful. &metdata_nl met_data_file =...

Hello, I want to change the dynamic variables, such as temperature or wind, in particular model time. I found that dyn_in and dyn_out are used to contain the dynamic variables, thus dyn_out%t3 represent the temperature field. But after I overwrite/change the values of the dyn_out%t3, it seems...

I have some issues with prescribing ozone produced from WACCM simulation as an input into CESM1-LE (CAM5). Specifically, I cannot get the model to read the ozone file in "SERIAL" mode (all 150 years). Here are the details of the run and errors. I use the B1850LENS compset from CESM1-LE with...

I would like to run the compset BRCP26C5CN with CAM5, but when I builded it the CESM told me that I was missing file https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/chem/trop_mozart_aero/emis/RCP26_mam3_pom_elev_2000-2100_c20130424.nc，RCP26_soag_1.5_surf_2000-2100_c20130424.nc...

I'm running CESM 1.2.2 with CAM5+trop_mam3+prescribed_emit ncl. After the task completed, I checked the atm.log file and cesm.log file and found these problems below: This is from atm.log file: And one from cesm.log file: It seems that some strange data have been written into the file, but I...

Hi there, I can successfully build a case, but after I submit the case, it completed very quickly (running about 5 minutes). I checked the atm.log file, it shows the problem below. I have checked the atm_in file and compared it with my script to check the variable name I used, and I didn't find...

Hi! I want to got the Total grid-box cloud ice water path (TGCLDIWP) or cloud water path for different tags. I added the output variable in the same way: fincl1="TGCLDIWP_NAO","TGCLDIWP_PAC"...... However, when I submit the simulation, it will report an error: FLDLST: TGCLDIWP_NAO in fincl( 1...

I am analyzing terms that contribute to the vertical mixing temperature tendency DTV in CESM1-CAM5, and in particular would like to get a measure for the counter-gradient flux of heat / non-local transport. slflx_cg is defined as kvh * cgh, the eddy diffusivity of heat times the counter-gradient...

Hi~ I used the iCESM1.2 to simulate water vapor from different regions. The results include precipitation(PRECC,etc), H2O isotope mmr for VAPOR,H2O isotope mmr for LIQUID, etc. How can I get the precipitable water vapor(PWV) from different source? Only the Total (vertically integrated)...

I am analyzing the temperature tendency contributions over continental North America and the ice-covered Arctic during winter in CAM5 (CESM1-CAM5, F_1850_CAM5 compset with prescribed SSTs and sea ice, constant pre-industrial CO2), often within the first couple of model layers near the surface. I...

Hello, I am running CAM5.3.01 (CESM 1.2.2) model and I would like to output far infrared variables from rrtmg and specifically the upward long wave flux (w/m2) (dimensions: (0:nlayers)) — totuflux. I changed the file /models/atm/cam/src/physics/rrtmg/ext/rrtmg_lw/rrtmg_lw_rtrn.f90, I attache...

Hi, everyone. I plan to conduct some sensitive experiments related to volcanic eruptions with CESM1.2(CAM5) and CESM2.2(CAM6). I have known that sulfur dioxides on behalf of a volcanic eruption can be input to CESM-WACCM, while the computing resources of WACCM are too huge. I wonder how the...
