VIIRS Data Transition Resources

Recommended options, guidance, and resources to support a smooth transition to alternative data sources for current Suomi NPP VIIRS data users.

Dataset Mapping

 

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 VIIRS 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 VIIRS products referenced on this page are hosted in NASA’s Earthdata Cloud (AWS us-west-2) and accessible via earthaccess.

AppEEARS

The Application for Extracting and Exploring Analysis Ready Samples (AppEEARS) is NASA Earthdata’s tool for point- and area-based extraction, reprojection, and transformation of supported geospatial datasets. AppEEARS currently supports VIIRS Land and snow cover products, as well as data from other missions including ECOSTRESS, EMIT, HLS, and PACE. Additionally, Landsat 4-9 U.S. Analysis Ready Data, Collection 2 Surface Reflectance Products are available in AppEEARS.

Not all VIIRS products are currently available in AppEEARS. If access to additional VIIRS and/or other products through AppEEARS would benefit your work, or any additional products are desired, please log in with your Earthdata Login account and let us know.
