What's New

  • 29 April 2014  The GADR NetCDF Format Updated to GADR-3.0

    The Global Argo Data Repository (GADR) serves the Argo data in the new GADR netCDF format (GADR-3.0) using lowercase letters for the dimension and variable names and still preserving the contents of the original Argo data. The enhancement of the global attributes section allow Argo dataset discovery and facilitate mapping between dataset metadata (notably netCDF) and ISO 19115. These conventions identify and define a list of NetCDF global attributes recommended for describing a NetCDF dataset to discovery systems such as Digital Libraries. Software tools will use these attributes for extracting metadata from datasets, and exporting to Dublin Core, DIF, ADN, FGDC, ISO 19115 etc. metadata formats.

    The GADR-3.0 format files (sample GADR3-0 netCDF format file) are fully in compliance with the Climate Forecast (CF) and Attribute Convention for Dataset Discovery (ACDD) conventions with the following global attributes beging added:
