cesm1

I tried to replace the system's own POP2 component with another ocean component on cesm1_3_beta17_sehires38, and created a case where compset was GIAF and res was f19_g16_rx1, but the following random errors occurred when the run process was repeatedly executed. May I ask why? Using the same...

Hi all, For some reason, I can't use cesm2 to run. But I got the spinup files from cesm2. I want to use those spinup files as the finit data to drive cesm1 for continue_run. It is possible？ What are the corresponding processes and steps？

Greatings, I would like to simulate climate change effects in Brazil using the CESM1 model (CMIP5). I am looking for CESM’s resolution information to realize regional dynamical downscaling with the WRF mesoscale model. According to information catched on NCAR Website, the CESM (CESM1) model...

Hi, I am using CESM version 1.1.2 to build the B20TRLENS compset. I have attached my config_machines.xml, config_compiler.xml and other machine-specific files. I am using the intel13 compiler with the following specs:- <compiler COMPILER="intel13"> <PNETCDF_PATH></PNETCDF_PATH>...

Hi All,I am trying to run the CESM 1.2.2 with the B_RCP8.5_CN compset. I was planning to run time slices 2045-2055. I am using the "trop_mozart" mechanism.  I have several error messages: 1) First, I have the error message of "ERROR: chem_surfvals_readnl: Cannot specify both bndtvghg and...

Dear all,CESM1/MESSy (geosci-model-dev.net/9/125/2016/) regrids import data online, using SCRIP, which requires the grid corners. These are available on yellowstone, e.g./glade/p/cesmdata/cseg/inputdata/lnd/clm2/mappingdata/grids/SCRIPgrid_ne16np4_nomask_c110512.ncbut are missing for the new...

The following reference was interpreted wrongly in terms of the maximum rate of soil respiration. This issue goes back to the introduction of CLM4.5 ! calculate the rate constant scalar for soil water content. ! Uses the log relationship with water potential given in <br />! Andren, O...

Just a heads up that the E1850LENS and F1850LENS compsets do not run out of the box from the special Large-Ensemble (LENS) tag. The fix is easy however. The "CO2" fields need to be removed from CAM's fincl list as co2_cycle is .false. in these compsets and the fincl variables are not recognized...

The intel 14 compiler causes a memory leak in the pop model in file diags_on_lat_aux_grid.F90The following change resolves the problem: --- diags_on_lat_aux_grid.F90(revision 64866)+++ diags_on_lat_aux_grid.F90(working copy)@@ -711,8 +711,11 @@         REGION_MASK_LAT_AUX(:,:,2) =...

The timing utility code in cesm1_2_2 and earlier (not sure how far back this goes) has a bug in perf_mod.F90 which results in no output being produced when the global statistics are turned off (via setting the namelist variable profile_global_stats=.false.). The fix is to change the value of...

Affected Releases CESM1.1.z and CESM1.2.z(Bugzilla 1861) There are some variables in the pop2 namelist that are set by build-namelist based on environment variables. For example, init_ts_option is usually 'ccsm_startup', 'ccsm_branch', 'ccsm_hybrid', or 'ccsm_continue' depending on the values of...

Affected Releases - CESM1.1.z and CESM1.2.z(Bugzilla 1877) Details included in the Bugzilla report.The check_input_data script does not grab POP's .hdr files (associated with binary data files) from the inputdata repository, so data is not read correctly on new machines until these files are...

Affected Releases - CESM1.2.z(Bugzilla 1717) For CLM4.5, I found one error that is not just a typo but also shows up in a rarely exercised portion of the code (most likely a sudden very intense snowstorm-- ~8 cm/hr -- preceded by warmer weather) in SLakeHydrology, where the top lake layer...

Affected Releases - CESM1.2.z(Bugzilla 1753) The file clmi.ICRUCLM45BGCCROPmp24.0241-01-01.1.9x2.5_g1v6_simyr2000_c130515.nc was interpolated using interpinic for CROP simulations. But, because of Bug 1725, interpinic gave a file that has CROP NOT spunup, but starting up from bare soil. So we...

Affected Releases - CESM1.2.z(Bugzilla 1634) It will map to other high resolutions like: ne120np4, 0.23x0.31, 0.47x0.61 however. The problem is that it does the mapping, but puts garbage data values (like e317) in some fields that the program does NOT touch. They happen to be very important...

Affected Releases - CESM1.2.z(Bugzilla 1759) - New good wood harvest is missing from some of the clm40 rcp datasets. A fix was provided in CESM1.1.2 but was not included in CESM1.2.1. In will be fixed in the next CESM1.2.z release.

Affected Releases - CESM1.2.z(Bugzilla 1776) - When running CLM45CNDV model (compset: ICLM45CNDV) and after running 400 years, there are no trees in the Amazon. ICNDV works all fine.The behavior has been attributed to Gordon's physiology changes to the model that improve the GPP simulation. This...
