// Data Collections

The NCCS houses curated data collections that include atmosphere, ocean, land, and flood data, both current and historical, as well as operational Global Modeling and Assimilation Office (GMAO) weather analysis data and forecasts that are updated four times daily.

COLLECTION TYPES

Our data collections are classified into two types:

  • Data Available Via Public Services
  • CSS Data (for internal use only)

// Data Available Via Public Services

Our public services help users find data holdings by model type (atmosphere, land, ocean, and coupled atmosphere/ocean), modeling project, and modeling organization.

CSS provides users internal access to centralized, commonly used data collections such as LANDSAT, MODIS, MERRA/MERRA2, and NGA*.

  • Datasets are not static–additional data is constantly being added.
  • *Access to NGA data and other non-public data collections require a signed agreement and adherence to specific usage policies.
