Thank you for your inquiry. Here are some instructions you might find useful:

Basic instructions for authenticating can be found here:

https://support.earthdata.nasa.gov/index.php?/Knowledgebase/Article/View/43/21/how-to-access-urs-gated-data-with-curl-and-wget

The exact sequence and syntax that I used:

        cd ~

        touch .netrc

        echo "machine urs.earthdata.nasa.gov login <username> password <password>" > .netrc

        chmod 0600 .netrc

   where <username> is your URS username and <password> is your URS password.

For wget (no clobber of existing files, all files downloaded into current directory):

        wget -nc -nH --cut-dirs 4 -r --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --keep-session-cookies --auth-no-challenge http://lance1.acom.ucar.edu/data/L2/

Please let me know if there are any obstacles. We will be happy to help you get the data.
