Re: [ferret_users] accessing ftp data from ferret

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi -
An FTP server is not the same as an OPeNDAP server.  You'll need to use FTP from your browser or the command line to download the data to your local disk and then you should be able to open it in Ferret as a local dataset.

To use OPeNDAP files in Ferret, you do not have to install your own copy of the netCDF libraries.  Those libraries are linked into the Ferret executable.  You can access data on OPeNDAP servers with Ferret,

yes? use "http://www.esrl.noaa.gov/psd/thredds/dodsC/Datasets/icoads/1degree/global/std/sst.mean.nc"
yes? show data

Hi,
  I want to access a large netcdf file (175 mb) from a ftp site. I installed netcdf using --enable-dap also. Even the command "nc-config --has-dap" also says "yes". I could even access some of the dods server files also in ferret. But when I am trying to access a netcdf file in ftp site, it is giving the following error.
**netCDF error
             NetCDF: I/O failure (OPeNDAP/netCDF Error code -68)
I used the following command:
use "ftp://username:password@ftpsiteaddress"

How can I overcome this error ?
Any help in this regard is appreciated.
