Where can I find land/sea mask fields for the CM2.X model grids?
If you are interested in GFDL’s CM2.X atmosphere and/or land model output, then you should be familiar with the IPCC Table O1b time-independent 2-d land surface data (longitude, latitude) files. A listing of our version of that table is found [ Here ]. Variable sftlf (land_area_fraction) is available both at the IPCC/PCMDI WG1 archive and on GFDL’s Data Portal. On the GFDL Data Portal this information is found in netCDF files found in the land/static subdirectories for all 20 experiments. The sftlf (land_area_fraction) information is identical for all CM2.X experiments. For example, on the GFDL Data Portal you may point your web browser to the directory http://nomads.gfdl.noaa.gov/dods-data/gfdl_cm2_1/CM2.1U-D4_1860-2000-AllForc_H2/pp/land/static/ …and download the file sftlf_A1.static.nc (a 59KB netCDF file that has been processed in accordance with PCMDI’s CMOR program.) If you are performing analyses using CM2.X ocean and/or sea ice model output stored on the model’s native tripol
