THREDDS Data Server

Submitted by ORNL DAAC Staff on

NASA's Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) is pleased to announce the release of a new THREDDS (Thematic Real-time Environmental Distributed Data Services) Data Server Catalog Service.

The THREDDS Data Server (TDS) catalog can be used for discovery and use of a limited number of field campaign; land validation; and regional and global data sets such as LBA, SAFARI 2000, ISLSCP II, MODIS Land Product Subsets, and data from flux towers. TDS allows users to find data sets that are pertinent to their specific research needs, access those data, and use them without necessarily downloading the entire file(s) to their local system.

The ORNL DAAC TDS is able to read data sets in various formats, and serve them through:

  • OPeNDAP,
  • OGC Web Coverage Service,
  • NetCDF subset, and
  • bulk HTTP file transfer services

TDS has the ability to aggregate many files into virtual data sets, which frees users from the many details of file storage and naming, and greatly simplifies user access to large collections of files. Additionally, OPeNDAP, OGC Web Coverage service, and NetCDF allow users to subset their data to be more easily analyzed and manipulated client side.

The ORNL DAAC is currently developing TDS access and visualization tools and increasing access to other data holdings. To learn more about our TDS, or to give it a try see our THREDDS Data Server Catalog Service page.
