Getting Started with Earth Surface Mineral Dust Source Investigation (EMIT) data in Earthdata Search
Note: Users must have NASA Earthdata Login to download data
Step 1. Go to Earthdata Search and Login
Click Earthdata Login in the upper right portion of the Earthdata Search Landing Page
Enter your Earthdata Login credentials (username/password)
- In the top left portion of the screen type in "EMIT" (quotes will limit results to an exact match). This will search for all available EMIT collections.
- Currently the LP DAAC manages two EMIT collections. EMIT L2A Estimated Surface Reflectance and Uncertainty and Masks 60m V001 and EMIT L1B At-Sensor Calibrated Radiance and Geolocation Data 60m V001.
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.
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.
- 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.
- If you are interested in only a single scene, click the download arrow on the card (or list row) for the select scene. You will then be able to download the select files related to that image.
You can also access S3 information (e.g., AWS region, bucket, temporary credentials for S3 access, and file names)
- To download multiple granules, click on the green + symbol to add files to the project. Click on the green button on the bottom of the page that says Download. This will take you to the options page for customizing the download.
On the next page click the Direct Download option and click the green Download Data on the bottom left side of the 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.
