Do the variables lat and lon from CLM output files mean the center location or the boundary location of a gridcell?

Hi

I am regridding a data product to the spatial resolution of clm. It's not clear to me whether the lat and lon in CLM mean the boundary or center location of a gridcell by checking the long_name of the two variables. Then I ncdump -v lat A_GLOBAL_CLM_OUTPUT_FILE.nc, and see the values of lat include -90 and 90 and the values of lon are from 0 to 358.75.

Does this mean that the lat and lon represent the boundary instead of center location of a gridcell?

Sincerely,
Xueli

Although I see why the lat values of -90 and 90 would make you think that they represent boundary values instead of centers, the answer is that these are center values in clm's output.
