Tokens for Downloading LAADS DAAC Data
A LAADS DAAC download token will help make file downloads faster, but is only usable for LAADS DAAC web sites. A LAADS DAAC token
will not work with other Earthdata sites.
Generating LAADS DAAC token …
Please copy and save the token below for use with any supported LAADS download utilities or scripts.
To test, run the following wget download command in your terminal and see if it successfully downloaded the README text file located at the root of the LAADS archive. See also LAADS documentation on how to use wget
We are currently unable to generate a LAADS DAAC token. Please try again later or contact MODAPS Support with any questions.
An Earthdata Download token (EDL) will work on any Earthdata site including all LAADS DAAC sites, but download performance from the LAADS DAAC can be much slower due to the extra network connections needed to check credentials at Earthdata.
Confirm Download of Multiple Files
Verifying login status…
Please confirm before starting this batch download of listed below totaling , one file at a time.
Once a batch download begins, your browser may not provide a way to cancel the batch aside from closing the browser entirely or stopping individual downloads one at a time. If in doubt, try selecting a smaller number of files for download. MODAPS Support is available to help with any questions.
Browser configurations
Some users might have to approve once (e.g., click "Allow") to allow for future downloads of multiple files.
To avoid a new download prompt for each file, ensure the following settings are configured in your browser:
Chrome: Settings > Advanced > Ask where to save each file before downloading > Off
Firefox:
