The function NF90_DEL_ATT deletes a netCDF attribute from an open netCDF dataset. The netCDF dataset must be in define mode.
function nf90_del_att(ncid, varid, name) integer, intent( in) :: ncid, varid character (len = *), intent( in) :: name integer :: nf90_del_att
ncid
varid
name
NF90_DEL_ATT returns the value NF90_NOERR if no errors occurred. Otherwise, the returned status indicates an error. Possible causes of errors include:
Here is an example using NF90_DEL_ATT to delete the variable attribute Units for a variable rh in an existing netCDF dataset named foo.nc:
use netcdf implicit none integer :: ncid1, status integer :: RHVarID ! Variable ID ... status = nf90_open("foo.nc", nf90_nowrite, ncid) if (status /= nf90_noerr) call handle_err(status) ... ! Find the IDs of the variables status = nf90_inq_varid(ncid, "rh", RHVarID) if (status /= nf90_noerr) call handle_err(status) ... status = nf90_redef(ncid) ! Enter define mode if (status /= nf90_noerr) call handle_err(status) status = nf90_del_att(ncid, RHVarID, "Units") if (status /= nf90_noerr) call handle_err(status) status = nf90_enddef(ncid) if (status /= nf90_noerr) call handle_err(status)
