nc_grid_mapping_atts(x, data_variable = NULL)open NetCDF object, character file path or url to be opened with RNetCDF::open.nc, or data.frame as returned from ncmeta::nc_atts
character variable of interest
tibble containing attributes that make up the file's grid_mapping. A data_variable column is included to indicate which data variable the grid mapping belongs to.
