The SNPP mission has restored data collection following a spacecraft anomaly that occurred on 26 July 2022. The VIIRS calibration team is evaluating the data to determine any impacts the two-week outage may have had on data quality. This evaluation may take several weeks to complete. Until such time as this analysis is complete and any calibration adjustments can be made, users are cautioned against using these data for scientific analyses.

Ocean Biology DAAC

Overview

The OBPG serves as a Distributed Active Archive Center (DAAC) for satellite Ocean Biology (OB) data produced or collected under NASA's Earth Observing System Data and Information System (EOSDIS), including those from historical missions and partner space organizations and is a member of the International Council for Science - World Data System (ICSU-WDS). This website thus serves as the primary data access portal to the NASA OB.DAAC. The links below provide a variety of methods to access the holdings of the OB.DAAC, including visual browsers that enable point-and-click access by data levels and direct access for bulk download. In agreement with partner organizations, some data access requires user registration to enable better tracking of usage metrics.

Data Management

The data management plan describes the acquisition, generation, management, archive and distribution of science data products generated by the Ocean Data Processing System (ODPS). For a detailed description of science data products, data flows, supported sensors, and data availability, archiving and distribution, please refer to the plan document.

Please be advised: Our data are undergoing a filenaming convention update. This process will occur over time, upon ocean color and sea surface temperature reprocessing for each mission.
