    how to regrid TLONG/TLAT pop data to regular Lon/Lat grid with python

    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...

    Very quick question about Paleotoolkit: gridkmt_nc2bin.f90

    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...

    case_run error,about issues mapping between components and grids

    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...

    Unable to build case with MUSICA regional refinement grid

    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...

    "Lagrangian levels are crossing" and "SIGSEGV, segmentation fault" error on custom grid

    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...

    Problem in initializing cesm2 with a new grid

    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...

    Adding a new grid for cesm2

    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...

    plotting the CAM-SE grid

    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?

    -grid_file equivalent for CESM1.3 (-user_grid_file)?

    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...
