A NetCDF implementation for glider observations

Within the Groom-EGO project, the definition of a NetCDF format for glider observations is underway.

The goal is to propose a data format that:

  • Is clear, understandable, and unambiguous for data users
  • Maximises interoperability i.e. uses existing standards to serve existing and new communities.
  • Contains sufficient metadata to enable legacy issues to be resolved should they be identified in future.

 

Groom glider User's manual

A document, derived from OceanSITES and Argo user's manual describes the management of :

  • Glider metadata
  • Glider observations
  • Glider technical data

The "EGO glider data User's manual" and glider deployment data files are available.

 

Quality control

The quality control applied in real-time is derived from Argo quality controls.

The tests applied on vertical profiles are:

  • Test 2 : impossible date
  • Test 8 : pressure increasing
  • Test 9 : spike
  • Test 11 : gradient
  • Test 13 : stucked value
  • Test 15 : greylist

 

Groom glider data processing

Groom matlab real-time processing chain provides quality controlled metadata, time-series and vertical profiles for Slocum, Seaglider and SeaExplorer platforms. Software, documents, configuration files managed on a SVN repository:
