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.
- EGO gliders NetCDF format reference manual: https://doi.org/10.13155/34980
- EGO ftp server, one directory per deployment : ftp://ftp.ifremer.fr/ifremer/glider/v2
- Example of SG558 glider deployment in Norwegian sea
- EGO is the "Everyone Glider's Observatory" initiative.
Quality control
The quality control applied in real-time is derived from Argo quality controls.
- EGO gliders Quality Control tests on timeseries and profiles data https://doi.org/10.13155/51485
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 available on:
- EGO gliders data processing chain https://doi.org/10.17882/45402
