The global attribute FILE_NAME contains the current data file name. This entry must be identical to the file name in the data archive. The FILE_NAME entry is always set in lower case, even if the field entries from which it is built are capitalized. Some data centers support HDF4, HDF5, and netCDF datasets. Correlative datasets in HDF4 format must have extension ".hdf", files in HDF5 format must have the extension " .h5" while files in netCDF format must have extension ".nc" (cf. Chapter 6).
Entry: Lower case, underscore separated + .[hdf|h5|nc]
