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.

TOOTSEA (Toolbox for Time Series Exploration and Analysis) is a Matlab software, developed at LOPS, IFREMER. This tool is dedicated to the analysis of data series from moored oceanographic instruments (current meters, CTD, Thermistor, ...). TOOTSEA allows the user to explore data and metadata from various instrument files, to analyze them using several available plots and statistics, to perform treatments/corrections and to qualify (automatically and manually) the data, and finally to export the work in a netcdf. doi 10.17882/59331 file. More information on this poster (2020, in French): Traitement & analyse de séries temporelles de mouillages océanographiques.

SoftwareCascade V7.2Analysis and monitoring chain for on-board acoustic Doppler current meterProcessing of ADCP hull dataMatlabv.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 dataMatlabv.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 toolAVISO+ Live 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 format Java 
 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.
