cesm output

I am trying to do a branch run based on the f.e21.FHIST_BGC.f09_f09_mg17.CMIP6-AMIP.001 restart files (1955-01-01-00000) with CESM2.1.5. The case was created and the model was built all successfully, but after ./case.submit I got the run aborted, with errors from the cesm.log as...

Hi, I have been trying to analyze the snow albedo ('albsno') and solar absorption ('fswabs') variables in CESM LE (where the cice component is on the 'g16' grid). Usually, I remap the pop data to a 1x1 deg. field with no issues; however, here, the data is split into the Northern and Southern...

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...

Hello, I am trying to run the "fixed sst" aquaplanet (compset QPC6 --res f19_f19_mg17) experiment on CESM 2.1.3. To explore if my control runs look the same or not I have conducted the same experiment twice without changing any configuration for 4 years and have discarded the first 6 months as...

Greetings, I am interested to find the differences between two CESM versions. In my local machine: cesm model version found: cesm2.2.0 While in Derecho : cesm model version found: release-cesm2.2.2 I have some modified modules from CAM which work fine in my local machine and I want to know...

When trying to clone release-cesm2.1.3, there is an error due to '/CFMIP/COSPv2.0/tags/v2.1.4cesm/src' path not found and the ./manage_externals/checkout_externals fails So, I modified "repo_url = Tags · CFMIP/COSPv2.0" --> "repo_url = https://github.com/CFMIP/COSPv2.0/releases/tag" in...

I find that co2 in CESM2 is bigger than other cmip6 models. 1st figure is CO2 in GFDL-ESM4, 2nd figure is CO2 in CESM2, 3rd figure is CO2 in MRI-ESM2-0 I compared models, then CO2 of CESM2 is bigger than others. But, co2mass of CEMS is same other models. Why CO2 of CEMS is bigger than others...

Hi~ I was running an I2000CLM50CN experiment recently and had a problem with the results. I first ran this experiment for ten years, and found that FCO2 presents a process from negative to positive. FCO2 is the value CO2 flux to atmosphere (+ to atm), so I think it is a net CO2 flux. While soil...

Dear all, My research involves wind resource evaluation, so I have to simulate the wind speed as close to reality as possible. The compset I use is 2000_CAM60_CLM50%SP_CICE_DOCN%SOM_MOSART_SGLC_SWAV_TEST, a all-active compset for long-term climate simulation. I choose the slab ocean mode to...

Hello, I notice that I can output these variables at specific pressure level directly by set fincl1='U200','V200','U850','V850','OMEGA500','OMEGA850'. But it seems UV at other level (like 700,500hPa) can not be gotten in that way. I konw it can be gotten output the whole level of U or V or...

Dear forum, I am downscaling CESM-DPLENS. I would like to know which ones of the CESM-DPLENS variables are equivalent to soil moisture (mrlsl in kg m-2), soil temperature (tsl), and liquid snow water equivalent (snw kg m-2) from CESM4 or how can I get those variables based on the available...

Greetings, I am looking, before I have to write a whole code from scratch, if there is available any package to interpolates pressure levels to a different set of pressure levels for a specific reanalysis files to be used in CESM2.2/CAM6. I found that there was a interpolation function in NCL...

Hi, I find it surprising that the same CESM2.2 CLM model output NetCDF file displays different "time" values when opened on different systems. Opening it using ncdump shows JANUARY: time:units = "days since 2015-01-01 00:00:00" while opening the same file by Python shows FEBRUARY...

Hi all, I am using the CESM2 Large Ensemble dataset and wanted to understand the "sea surface height" variable, SSH_2. The dataset is in /glade/campaign/cgd/cesm/CESM2-LE/ocn/proc/tseries/day_1/SSH_2/. Is SSH_2 supposed to be the "dynamic sea level," referred to as "zos" according to CMIP6...

Hello, I am trying to look for monthly-mean near-surface air temperature / 2m air temperature data from the CESM1 control runs (ideally for the coupled and slab ocean experiments). The short name of this seems to be TSA (as listed here Output Variables | Community Earth System Model) but I...

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)...

Hi all, I've been working with some PFT-level data from CLM5 (e.g. NPP for each PFT) and have been using Python code from the NCAR-ESDS documentation to do the processing (Sparse arrays and the CESM land model component — NCAR-ESDS 0.1 documentation). This worked great until this week and I am...

I am planning to do some F-compset runs of CESM2 at fixed CO2 that cover multiple decades and need history output for multiple large variables like temperature and winds at high time resolution (every hour). The history files take up a lot of space, and writing the files seems to slow down the...

Hi all, I'm working with the 1D PFT-level output for CLM5 for the first time. I am interested in plotting a timeseries of some PFT-level variables over my domain. I can see in the variable list that my history files contain a variable called 'pfts1d_wtgcell' (PFT weight relative to...

I am using CESM 2.1.3. I have found how to output high frequency data in CAM, CLM and etc in CESM Tutorial. However, there is no information on how to output CPL variables. As shown in the figure below, I have found some clues on the CESM CPL namelist webpage. I guess the variable names...
