Instructions for how to use the download access script provided by Earthdata Search, which allows users to easily download large numbers of files.
IMPORTANT: The download access script works on Mac and Linux systems. It also works on Windows systems with any program that emulates a Unix command line, such as Cygwin.
Add the steps involved:
After downloading the script, open a terminal window and navigate to the folder that contains your script
The files downloaded by this script will be downloaded to the folder that your script is in. If you want your files downloaded to a specific folder, please make sure to move the script to that folder before executing the script. |
Next, run the following command to make the script executable:
chmod 777 download.sh |
Now that your script is executable, run the script using the following command. (Note: the leading period and forward slash is required.)
./download.sh |
The script will ask for your Earthdata Login credentials.
Note: your Earthdata userid and password are case-sensitive, so be sure CAPSLOCK is off. |
When asked for your Username, please enter your Earthdata userid.
When asked for your Password, please enter your Earthdata password. When entering your password, you cannot see your password as you type. This is a Unix convention for security, but it can be confusing.
After entering your password, be sure to hit the RETURN key.
A simple alternative to the script is to use wget as follows:
where myusername is your Earthdata username, mypassword is your Earthdata password, and url_list.txt is a text file with one granule download link per line.
Another alternative, especially in Windows environments, is to use DownloadThemAll!, an add-in for the Firefox browser. (TIP: By adding .txt to the end of the download script, you can use DownloadThemAll!'s "import from file" feature to download the links it contains.) |
Connection failures like "Operation timed out" or "No route to host" are an indication that the data provider's server may be temporarily unavailable. To see a list of known data provider outages, click the alerts button (the little bell icon) in the upper right-hand corner of Earthdata Search. |
When running the script, if you get the error
this means the curl command is not recognizing the option --netrc-file. The --netrc-file option was added in curl version 7.21.5. You can check your version of curl by running the following command:
If your version of curl is less than 7.21.5, you need to update curl. |
