Sorry, we don't have even any rough estimates of that sort.

It might be of interest that the $10B GOES-R project has selected
netCDF-4 for representation format of all ground-segment data, which 
will ultimately be petabytes.  The CMIP5 archives for the IPCC are
also mandated to be netCDF with CF conventions, which will also be

The only recent usage statistics I know of, presented to our governing
committees, are these:


which require lots of clicking on links to drill down to numbers for netCDF, 
such as 85000 downloads/year, 117 countries, over 900 support replies/year,
and over 1 TB/month of data downloaded from out THREDDS service (TDS).

There are a few more usage statistics at the end of this netCDF status report:


including links to a few more detailed metrics.
