All datasets have the flux data stored in a three-dimensional array structure with dimensions of grid cell number (0 - 515), flux number (0-10), and time (depending on dataset, 0-11 for monthly or 0-364 or 365 (leap year) for daily):
Flux files have been saved in HDF (version 4.0) format. Each HDF
file contains data for one year, for one polar region, for either monthly
or daily averages. Within each HDF file, there are three datasets:
Fluxes, Latitude, and Longitude, all of which can be accessed with standard
HDF routines. Each dataset also has label and unit attributes, and
the dimensions have a name attribute. Sample IDL code to extract
the data and labels is in IDL and C programs listed below the data table
in the next section. Also, if you do not have access to IDL, there
are various command line HDF utilities which can be used to extract datasets;
see the NCSA HDF web site for details
and code.
Only daily and monthly averages are available for web download. Special
requests for three-hourly data will be handled on a case-by-case basis.

To download a single file you'll probably need to right-click the file name then choose "Save link as" or something similar. Or you can go to the ftp site if you prefer.
