    CESM O3 hourly output

    Hi, I am currently using CESM2.1.3 (CAM4, CLM5), FMOZ compset. I want to get O3 hourly output in the hist file and the rest of the other variables in the monthly output (default). I made some changes in user_nl_cam, but I am still getting h0 files as model output and on checking the output .nc...

    Help requested: strange error in CESM2 run

    Background We are trying to run CESM2 job on Cheyenne, version release-cesm2.1.3, WACCM MA. The goal is to conduct a simulation of stratospheric aerosol geoengineering, branching from a "background" run in 2035. The first year of simulation runs successfully, but every time we submit the second...

    [Question] Different namelist for CO2 concentration in F compset and B compset ?

    Hello, I'm PhD student who just start studying CESM2 modeling. Basically, I've studied and followed CESM2 Tutorial materials which are available freely online. I could learn the way to change CO2 concentration by changing "co2vmr" namelist with B compset example. Then now, I would like to change...

    surfrd_get_data ERROR: sum of wt_lunit not 1.0

    Hi, I am running CESM2.1.3 with FMOZ compset, trying to see the impact of landcover change. I keep on changing "PCT_NAT_PFT", "PCT_NAT_PFT+PCT_CFT" and "PCT_NAT_PFT+PCT_CFT+PCT_CROP". Making change on the first two runs well, but when I change PCT_CROP along with PCT_NAT_PFT & PCT_CFT, there is...

    Finding HDIFE_TEMP, HDIFN_TEMP, KPP_SRC_TEMP in CESM2

    I'm currently trying to create a simple heat budget from the CESM2 ocean data linked below but couldn't find some of the variables included in the CESM1 monthly ocean data set. Specifically I am looking for the HDIFE_TEMP, HDIFN_TEMP, and KPP_SRC_TEMP variables. I found the vertically integrated...

    What can and cannot be changed post-build

    I am used to making changes to user_nl_xxxx after a CIME case has been built, which as far as I know, is fine since namelists are always generated at runtime. Can I also do this with env_*xml variables, via xmlchange? Or does xmlchange need to be used only pre-build? All I am trying to do is...

    CESM2.0 output meteorological data from CMIP6

    Hello Folks, I’m wondering whether someone has an idea about the data availability of CESM2 output meteorological data (e.g., air temperature, precipitation, radiation, wind, pressure, etc.) at 3- or 6-hourly time step from CMIP6 project. I have checked the Earth System Grid Federation (cmip6 -...

    Pointing to a custom namelist file for a given run

    I have created a CIME case, which has been setup and built. As I understand, the namelist files user_nl_xxxx can be edited post-build. If I want to vary a namelist setting X across several runs, I can do that by 1) Running CESM 2) editing X=... in user_nl_xxxx 3) Run again Two problems... 1)...
