We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

ASF DAAC Data Access and Tools
Please note: As part of the Web Unification Project, we are working to import all datasets archived by NASA’s Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) into our catalog. During this transition, you can also access their datasets by DOI on their website. Access a list of dataset DOIs at ASF DAAC
ASF DAAC provides the Earth science community with global synthetic aperture radar (SAR) data. Explore ASF DAAC datasets and learn more about relevant data tools. If you need to download lots of data at once, see ASF DAAC's bulk data download options and related tutorials.
NISAR sample datasets are available through ASF DAAC so you can explore data formats, test workflows, and prepare your tools ahead of the mission’s full release. These examples help users become familiar with NISAR data and learn how to integrate it into their research or applications.
