Data Access

Earthdata Search and CMR

NASA's Earthdata Search is the primary web interface for discovering, visualizing, and accessing NASA Earth Science data. The Common Metadata Repository (CMR) provides the metadata and API layer that supports both interactive searches and programmatic workflows. All CrIS products referenced on this page are discoverable and accessible via the Earthdata Search Web Interface or programmatically via the CMR Search API.

Earthaccess

The earthaccess Python library provides a simple way to authenticate, search, and access NASA Earth science data programmatically, making it especially useful for scripted and cloud-based workflows. All CrIS products referenced on this page are hosted in NASA’s Earthdata Cloud (AWS us-west-2) and accessible via earthaccess.
