You can save the data returned from that url as a .nc file using ncdump. However, the result will probably not be identical to the original ocean_v_2008_05_12.nc file because it will still be converted to dap before being converted again to .nc format. If you need the original .nc file, you will have to contact the site that is storing it, which in this case is apparently www.marine.csiro.au =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: NVO-718407 Department: Support THREDDS Priority: Normal Status: Open
