Tools and softwares

All the data collected via the various observation services and networks requires validation before being used and enhanced. Scientific expertise can be based on a set of tools and software, made available to process, compare, extrapolate, visualize and validate a set of data so that they can be used in research publications and reports or introduced into models (long-term visualization, climate prediction, etc.). Among all these tools and software, three types are available within the ODATIS cluster:

  • Softwares consist of a set of programs, processes and calculation rules that form a complete chain for processing a data set. These are accessible and downloadable online.
  • Tools are particular elements that can operate without software and meet a specific processing need. These are also accessible and downloadable online.
  • The online tools are identical to the tools previously presented, with the exception that the latter cannot be downloaded and installed on private servers. These tools only allow the user to access and visualize the data and/or results obtained from the online data.
TypeNameBrief descriptionFunctionLanguageLicence
SoftwareCascade V7.0Analysis and monitoring chain for on-board acoustic Doppler current meterProcessing of ADCP hull dataMatlab v.2008b
Through the Matlab software, Cascade allows the processing and analysis of hull ADCP measurements made during offshore campaigns or transits carried out at sea by Ifremer, SHOM and IRD oceanographic vessels. It allows the "cleaning", filtration and visualization in different forms (vector, etc.) of the current data.
Processed format: NetCDF, TAR
SoftwareTSG-QCThermoSalinoGraph - Quality ControlInteractive quality control of both surface temperature and salinity dataMatlab v.2015b
TSG-QC allows the visualization of the variables acquired by TSG (Seabird thermosalinograph): temperature, salinity and vessel speed and their comparison with climatology values. This software has been designed to facilitate data control and validation (assignment of quality codes and application of threshold criteria), calibration and correction of acquired data (quantitative estimation of sensor drift and correction from independent data).
Processed format: ASCII, NetCDF, SODA
Online toolISAS-ViewerIn-situ analysis system - ViewerVisualization of the temperature ranges resulting from the ISAS analysisPythonExecuted online
ISAS-viewer is an online tool that allows the online visualization of horizontal maps of a set of variables derived from the temperature and salinity fields produced by the ISAS optimal interpolation tool. This tool also allows the visualization of absolute fields and anomalies related to a climatology at different levels.
Online toolLive access ServerView gridded altimetry satellite data (L4)Mapping, comparingOpendap, FerretExecuted online
The Live Access Server allows users to: map data, request data set extractions in different formats, view reference information (metadata) on data sets, compare data sets available on different remote servers, perform basic statistics (mean and variance) such as plotting a monthly average current map in the desired area.
SoftwarePanoplyView all types of data in NetCDF, HDF and GRIB formatJava
Panoply allows you to view, map files previously downloaded or from remote servers (THREDDS, Opendap), consult reference information (metadata) on data sets, export in KMZ, make animations in MP4 format.
ToolNetCDF Operator NCOHandling NetCDF and HDF files
NCO includes a set of online commands to be executed to view and modify reference information (metadata) on datasets, to perform calculations on the variables contained in the file (average for example), to print, and to export the values from these files.
SoftwareParaviewView, manipulate, edit files of various formats
ParaView is a free software for 2 and 3 dimensional data visualization, designed to run on both Windows and Unix environments. The data formats taken into account are very varied. A highly scalable graphical user interface allows you to edit multiple graphics simultaneously: 2D/3D map views and, at the same time, adjacent 2D graphics. For recurring processes or post-processing of data, an adjacent interface allows the creation and execution of Python scripts.
