Data Management & Tools


EGO gliders data processing chain

The EGO data processing chain decodes, processes, formats and performs quality control on glider data and metadata. The decoder performs the following actions for a glider deployment:

  • Decode and format the glider deployment data and metadata into an EGO NetCDF time series file
  • Apply Real Time Quality Control (RTQC) tests on EGO NetCDF time series file,
  • For Slocum gliders, estimate subsurface currents and store them into the EGO file,
  • Generate NetCDF profile files from EGO file data and apply specific RTQC tests to them.

The decoder manages Slocum, SeaGlider and SeaExplorer gliders observations.

IOOS National Glider Data Assembly Center Wiki

This wiki is a collection of documents and resources describing the NetCDF file specification, data provider registration and data set submission processes for contributing real-time and delayed-mode glider data sets to the U.S. IOOS National Glider Data Assembly Center (NGDAC).


A toolkit for processing Seaglider base station NetCDF files: despiking, smoothing, outlier detection, backscatter, fluorescence quenching, calibration, gridding, interpolation.

IOOS Quality Control

Quality Assurance of Real Time Oceanographic Data (QARTOD) and other Quality Control tests implemented in Python.


GLIDERSCOPE is a standalone Win/Mac software package designed to give you the power to visualise glider data effortlessly via a convenient graphical user interface. By using the freely available GLIDERSCOPE software, anyone can examine NetCDF files they have downloaded, filter out bad data, interactively isolate segments of data and apply a variety of useful data graphical visualisation techniques to examine the data.

EGO Glider Data Management Page

Here are some documents that relate to EGO data management.

EGO gliders user’s manual NetCDF conventions and reference tables Version 1.0

This document specifies the NetCDF file format of EGO-gliders that is used to distribute glider data, metadata and technical data. It documents the standards used therein; this includes naming conventions as well as metadata content.

Good procedures to manage OceanGliders data with Coriolis

This document specifies the good procedures for gliders data management if Coriolis is your Data Assembly Centre (DAC) or Global DAC.
