Hi Ben, Welcome to Ferret! There is an example of how to access a NetCDF file from a DODS server in the Ferret Users Guide; look up "DODS, accessing remote data" in the index, which points to Ch2 Sec7.2. Here is the example from the Users Guide, yes? USE "http://www.ferret.noaa.gov/cgi-bin/nph-nc/data/coads_climatology.nc" ! Once the dataset has been initialized, it is used just like any other local dataset. yes?

NetCDF is the recommended format for Ferret, and the Ferret command SAVE is an alias to FILE/FORM=cdf . So after opening the data set you might do something like this: yes?

I want to use Ferret to access data from a remot e DODS server, and to then write that data into a file (in either acsii or n etCDF format) on my own computer as a local file. Can anyone tell me the se quence of commands to do that (or maybe just send me a script that can perfo rm this, that will show me an example of the process)?
