NetCDF file format

NetCDF4 (Network Common Data Form) is a data model, API library (application programming interface) and a file format. It is used for storing and managing data. It is developed and maintained by Unidata. Unidata is part of the US University Corporation for Atmospheric Research (UCAR) Community Programs (UCP). Unidata is funded by the US National Science Foundation.

SONAR-NetCDF4 is a data and metadata convention for storage of data from active sonars in NetCDF4 formatted files, defined by The International Council for the Exploration of the Sea (ICES). Sonar-NetCDF4 consists primarily of a naming convention and a data structure within the NetDCF4 data model. The ADCP-NetCDF4 is based on the SONAR-NetCDF4 version 1.0 and extended with additional data and metadata to store ADCP data.

The echo sounder NetCDF4 information uses SONAR-NetCDF4 version 1.0.

SONAR-NetCDF4 convention version 1.1 has been extended to store split beam echo sounder data. The SONAR-NetCDF4 convention has also been extended with additional data and meta-data to store ADCP data. For the latest update of the convention please visit:
