wget for Windows

1.Make sure you have setup your Earthdata account.

2.Install wget if necessary. A version of wget 1.18 complied with gnuTLS 3.3.3 or OpenSSL 1.0.2 or LibreSSL 2.0.2 or later is recommended.

3.Create a cookie file. This file will let you download GES DISC resources without having to re-login.

a.Open a run-command window by pressing WinKey + R

b.Next, enter "cmd" in the text field and click "OK"

c.Navigate to the directory you wish to create the cookies file in. In this guide, we place it under the C drive, but any directory will do. You can navigate to the C drive by entering C:

d.Finally, enter NUL > .urs_cookies.

Note: you may need to re-create .urs_cookies in case you have already executed wget without valid authentication.

Note: you can get 'Access denied' error. Enter 'dir' to verify that '.urs_cookies' file is listed in your directory.

4.Download your data using wget:

wget --load-cookies C:\.urs_cookies --save-cookies C:\.urs_cookies --auth-no-challenge=on --keep-session-cookies --user=<your username> --ask-password --content-disposition <url>

a.--auth-no-challenge may not be needed depending on your version of wget

b.<your username> is the username belonging to your Earthdata account

c.<url> is the link that points to a file you wish to download or to an OPeNDAP resource.

d.Your Earthdata password might be requested on the first download

e.If you wish to download an entire directory, such as this example URL, use the following command:

wget --load-cookies C:\.urs_cookies --save-cookies C:\.urs_cookies --auth-no-challenge=on --keep-session-cookies -np -r --content-disposition <url>

To download multiple data files at once, create a plain-text <url.txt> file with each line containing a GES DISC data file URL. Then, enter the following command:

wget --load-cookies C:\.urs_cookies --save-cookies C:\.urs_cookies --auth-no-challenge=on --keep-session-cookies --user=<your username> --ask-password --content-disposition -i <url.txt>
