grids

Hello, I am working with the FWsc2010climo compset. The default resolution is f09_f09_mg17. For my application, I would like to use a more regular ~1° × 1° grid instead. From what I understand, this would require regridding all of the input data (initial conditions, prescribed ozone, CO₂...

I have seen this question unanswered in the forum. I am using CESM2LENS historical and SSP3-7.0 to process monthly ocean temperature and salinity data. The TLONG embedded in the netcdfs are missing values from 95-140 deg, and I need this data for indexing. See file...

Hello, I am trying to run an experiment using the F2000climo reference case with a T42_T42 resolution instead of f09_f09_mg17 resolution, i.e. I want a low-resolution equivalent version of my previous experiment. I created a new case like so: ./create_newcase -case...

Hello, Is there a "best practice" way to regrid POP output from the TLONG/TLAT grid to a regular (e.g., 1x1 degree) grid? My naive approach would be: loop over all combinations of lats / lons on my desired 1x1 deg grid collect all Tlong/Tlat gridcells within 0.5 deg of the given lat/lon...

Hi NCAR paleo friends, Recently I am using the NCAR paleotoolkit to create a binary KMT file from a .nc one. I used this code: https://github.com/CESM-Development/paleoToolkit/blob/master/cesm1_2/ocn/mk_ocn_grid/gridkmt_nc2bin_src/gridkmt_nc2bin.f90 However, when I look at Line 37, this...

Dear Helper, I want to run a case with 'f09_g16' grid and 'FMOZ' compest in CESM1.2.2, the default FMOZ suits with 1.9x2.5, so I modified the file '2000_cam4_trop_chem.xml' to match with f09_g16, but there is still a error about SST and ice coverage data, it shows "application called...

Hi all, I've made a regionally-refined grid using MUSICA by following the steps in the tutorial. However, case.build fails with: ERROR: Could not initialize Grids when I try to build the case. It's a case using the FCHIST compset and I'm running CESM2.2.0 on Cheyenne. I'm not sure where to...

Dear All, I'm trying to run an aquaplanet (QPC6, a compset I have used extensively with f19 resolution) simulation on a custom grid using CESM 2.1.3, but the case fails on execution. I have setup a custom 2x20 grid ( actually ~1.9x20 with nlat 96 and nlon 18 ) following 3.2 of these...

Dear All, I'm trying to run an aquaplanet (QPC6, a compset I have used extensively with f19 resolution) simulation on a custom grid using CESM 2.1.3, but the case fails on execution. I have setup the custom 2x20 grid following 3.2 of these instructions and with guidance on this thread. I am...

I have been using CESM 2.1.1 in the aquaplanet setting for certain idealized studies. In this regard, I would like to perform certain experiments with a very coarse resolution in the longitudinal direction, say, for example, maybe a dlon of 15 ~ 20 degrees. In this regard, I have been following...

Affected Releases - CESM1.2.zFixed in CESM2.y.z----------------------There is a small typo in the"config_grid.xml" file in $CCSMROOT/scripts/ccsm_utils/Case.template/".It should be "fv0.9x1.25" instead of "fv0.9x.125" in Line 1066. 

Hi, I wanted to plot the CAM-SE grid, but I don't get a grid of evenly square-sh cells, but rather a mix of squares and rectangular cells. I've attached a plot of the topography with red gridlines.Is this how the grid is suppossed to look?Could I be plotting it incorrectly perhaps?

Hi there, I am trying to get a new grid set up (for I and IG simulations on the regional RASM model grid). In CESM1.2, the create_newcase command accepted as an argument the name of an xml file, to define the grid for the executable. I have pasted the contents of this file, as I created it, at...
