CESM2 land-sea mask

[mrdo3197]

Hi, I downloaded the CESM2 surface altitude data (variable name "orog") from the CMIP6 page https://esgf-node.llnl.gov/search/cmip6/ and when I plot it I get the result shown below, as you can see there is some data surrounding the continents that it is suppose to be ocean so I would like to know if there is a land sea mask file (if possible an .nc file) for this model so I can correct this or if what I got it's how it is suppose to be. Thanks.

The variable you want is "sftlf" ("Percentage of the grid cell occupied by land (including lakes)"), not "orog". Each experiment has an "sftlf" netCDF file available via ESGF as you found "orog".

Let me know of any other questions.

Thank you so much, that's what I was looking for.
