Select the collection of granules that you want to view. If you are unsure which collection to choose the View Collection Details offers more information about each data product. The current state of the collection includes a very limited data release with only a handful of scenes from select locations.

Step 3. Download EMIT Data

To view the scenes and location, click on the image to focus it on the map the location is indicated by a green box. A preview of the scene is shown on the right.

  1. If you are interested in downloading all EMIT scenes discovered by Earthdata search, select the Download All icon at the bottom of the search results page.

The final page of instructions show the download links for data access in the cloud. You should see four tabs: Download Files, AWS S3 Access, Download Script, and Browse Imagery.

The Download Files tab provides the https:// links for downloading the files locally

The AWS S3 Access tab provides the s3:// links, which is what we would use to access the data directly in region (us-west-2) within the AWS cloud.
