UCAR FTP server

Uploading files | Downloading files

Authorized UCAR persons and NCAR personnel (individuals who have valid NCAR scientist and project numbers) can use the UCAR FTP server to share files with anyone who needs to download them if no secure method is available.

This server should not be used for data storage.

To request an ftp.ucar.edu account, email the CISL Help Desk or submit a help ticket. You will receive your password by email when your request has been fulfilled.

Uploading files

To upload files:

Log in to ftp.ucar.edu with your FTP client (see image) or by entering the following at your command line.

ftp ftp.ucar.edu
UCAR ftp
When using FTP client software such as WinSCP or FileZilla, be sure to select FTP and specify Port 21 rather than SFTP and Port 22 to log in to ftp.ucar.edu.

Execute the usual FTP commands* to put the files in your login directory or in the /pub subdirectory to which you have been given write access.

Notify the intended recipient of the full path name to make the files easy to locate, and suggest downloading them as soon as possible.

Remove the files from the server once the recipient has downloaded them.

Keep in mind that anyone can access files kept on the server in a public folder.

Do not store sensitive or critical data there.

Downloading files
