Find Data with ASF Vertex and API Search

The ASF DAAC offers two ways for you to search and download data: through the ASF Vertex application and through the ASF Search API.  In either case, it will require you to create a free Earthdata Login account first at the Earthdata website to be able to download the data.  The credentials will provide you access to the Vertex Search and API download functionality, which will allow you to download data as a single download or a batch download.
