## Data Access

Refer to the [Downloads](../using/downloading.md "hyp3-docs.asf.alaska.edu/using/downloading")
ARIA S1 GUNW On-Demand products can be accessed like any other On-Demand product, but can also be accessed by
searching the archive.

### Accessing Products using On Demand Interfaces

Refer to the
[Downloads](../using/downloading.md "hyp3-docs.asf.alaska.edu/using/downloading")
page for more information on viewing and downloading ARIA S1 GUNW On Demand products in Vertex or programmatically.
Once processing is complete, download links for On Demand products are valid for 14 days.

### Accessing Products in the Archive

Once the submitted jobs have been processed, they are added to the archive of ARIA-S1-GUNW products. Use the
[Geographic Search in Vertex](https://search.asf.alaska.edu/#/?maxResults=1000&dataset=SENTINEL-1%20INTERFEROGRAM%20(BETA) "ASF Search for ARIA S1 GUNW Products" ){target=_blank}
to find all of the products (both those generated by the ARIA project and those generated On Demand) available for your
area of interest. The download links for these datasets (including those generated On Demand) never expire.

You can also search for ARIA S1 GUNW products programmatically using the
[asf_search Python Package](https://pypi.org/project/asf-search/ "pypi.org/project/asf-search" ){target=_blank}.
Again, results will include both the products generated by the ARIA team, along with any On Demand products that have
completed processing.
