#### Step 4b. Download or data access for multiple granule

To download multiple granules, click on the green **+** symbol to add files to our project. Click on the green button towards the bottom that says "Download". This will take us to another page with options to customize our download or access link(s).

On the next page click the **Direct Download** option and click the green **Download Data** on the bottom left side of the page. In this page some datasets will provide a data customization service, this is really important if we don't want to download the full record but just the variables and region of interest.
