### Accessing data using your copy of ferret

DODS allows one to give a application a url and have it directly download data. To read this data into ferret use
set data "http://iridl.ldeo.columbia.edu/SOURCES/.IGOSS/.TOPEX/.NOAA/.ssha/T+differences/yearly-climatology/Y+differences/%5BY+%5Ddetrend-bfl/Y+integral/X+integral/Y+integral/T+integral/X+integral/dods"

If ferret refuses to read the file, saying
** netCDF error: Invalid Argument
is this a CDF file ?

it is quite possible that you can use **set data** after you download the netcdf file.
If you have questions, comments, or problems please use the help@iri link.
This page will evolve as we learn more about how Ferret handles data downloads, and your help pointing out problems is much appreciated.

There is a bug in ferret which is corrected in release 6.0 (see notes about "nonstandard calendar axes"). Please upgrade if you are using monthly data.
