    Output variable of evaporation and precipitation in CAM6

    Hi, I want to plot "precipitation - evaporation" using the simulated CAM6 data. So, I will change user_nl_cam. However, I couldn't find the evaporation variable. Through the "CAM history field ("...

    Finding an output variable to enable to calculate MOC strength

    Hello, I am looking to calculate the MOC strength and a colleague recommended that there may be an output variable that can be enabled through the namelist that quantifies AMOC strength as an already defined output of the model. After looking through the namelist for the ocean variables I can't...

    (shr_sys_abort) ERROR:phys_ctl_readnl: ERROR reading namelist

    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...

    How to switch off a namelist variable

    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...

    Running 2015-2100, rather than 2000-2100

    Hi, I would like to do a transient run of CESM2.2.0 over the period 2015-2100 using SSP3-7.0. I plan to use a transient land use change scenario in CLM5 ('flanduse_timeseries'). However, the namelist setting 'sim_year_range' in CLM5 only permits running over the period 2000-2100. As I'm not...

    Namelist read error caused by 5004 error when trying to run modified code on UCSC system

    Hi there, On cheyenne, have succesfully run a modified case where I have added longwave flux into the sea ice model. An example can be found at /glade/u/home/mre2126/cesm2_cases/AquaSOM_icersnw.80_1850_GFm50_h30_Qflux1850NHSH_symaero_fix8 which includes the SourceMod files. I have also added...

    Icepack - 1) altering the namelist icepack_in and 2) cases/tests/runs

    I have a two main questions about basic runs in Icepack (version 1.3.0). Ultimately I wish to perform a few Icepack simulations altering the model a little. A successful run ============= If I follow the user guide: 3.3. Testing Icepack — Icepack documentation And perform e.g. a single...

    Changing Q10 in user_nl_clm

    Hi, I'm running PTCLM with the 2000_DATM%1PT_CLM50%BGC_SICE_SOCN_MOSART_SGLC_SWAV compset, and I want to change the Q10 value for frozen and unfrozen soils. I can change the q10 for frozen soil by adding froz_q10=newvalue to the end of my user_nl_clm file, but when I add Q10=newvalue (to...

    comments in user_nl_cam

    Can comments be added to namelist files, e.g. user_nl_cam, that will be ignored upon model build? I can't seem to find documentation on this.

    [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...

    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)...
