 Example: [ATLAS/ICESat-2 L2A Global Geolocated Photon Data. (ATL03, Version 7) Landing Page](https://nsidc.org/data/atl03/versions/7). In the right-hand menu on a data set landing page, click "Data Access & Tools".  You will be directed to the top of a list of tool and service "cards" with links to various data access methods.  Click on the card title "Data Access Tool" to be directed to the Data Access Tool interface for that particular data set.  The Data Access Tool allows users to filter files within a data set using spatial bounds, temporal ranges, and filename wildcards.
