3.3.3 Inquiry in Fortran 90

First use NF90_INQ, which will tell you how many variables and global attributes there are in the file. Then start with varid 1, and proceed to varid nvars, calling NF90_INQ_VAR.

For a typical sequence of calls to these functions, see See Reading a netCDF Dataset with Unknown Names.

NF90_INQ. Find number of dimensions, variables, and global attributes, and the unlimited dimid.


NF90_INQ_DIM. Find dimension name and length.


NF90_INQ_VARID. Find variable ID from its name.


NF90_INQ_VAR. Find variable name, type, num dimensions, dim IDs, and num attributes.


NF90_INQ_DIMID. Find dimension ID from its name.


NF90_INQ_DIM. Find dimension name and length.


NF90_INQ_ATT. Find attribute name, type, and length.


NF90_INQ_FORMAT. Find file format: classic or 64-bit offset


NF90_INQ_LIBVERS. Find the netCDF version. (Currently 4.0-snapshot2008082116).
