You can download multiple collections, individual collections, selected granules or individual granules.

After clicking "Download Data" or "Configure and download single granule data," you will see one or more of the following options, depending on what the data provider allows for that collection:

1) Order Data | Direct Download
Allows you to download data as-is now from your browser, either by accessing a list of download links, by downloading a file of data links for offline processing, or by downloading a script that can be used with curl or wget. 

2) Order Data | Stage for Delivery
Allows you to submit a request for a staged delivery.  
You will receive an email with download instructions when the data is ready.

3) Order Data | Customize Product
Allows you to select custom service options to be performed (e.g. subsetting, reprojection, etc.)
You will receive an email with download instructions when the data is ready.

To download multiple collections, use the + button to add collections to a "project" (similar to a shopping cart), and then click the "My Project" button.
