AEROLAB SPACE is a decision support tool for regional authorities to monitor GHGs on a regional scale and give credibility to decarbonisation efforts. The tool based on the synergy of in-situ (ground, aeroplane, balloon) and satellite data sets, which until now have not been available in France, makes AEROLAB a flagship project in terms of adaptation and mitigation of climate change.

Space component of the AEROLAB research cluster


The AEROLAB research cluster, currently supported by the University of Reims and the CNRS, supports low-carbon technologies (monitoring and validation of emissions on industrial/agricultural sites) and public policies to reduce GHGs (greenhouse gases) in cities/metropolises, carbon storage (reforestation) and waste management and water purification.  Currently funded by various partners, AEROLAB aims to provide expertise and solutions for the monitoring and analysis of atmospheric emissions in the Grand Est region and beyond. AEROLAB is part of regional initiatives with strong links to, among others, ATMO Grand Est, Planet A and AERIS.

As an extension of this initial project, we propose here the Space component with AEROLAB SPACE, which will create a synergy between AEROLAB's in situ measurements (ground, aircraft, balloon, etc.) and measurements from satellites. AEROLAB SPACE will thus be a decision-making tool with indicators for monitoring GHGs on a regional scale and evidence of the impact of environmental policies. These results will benefit public authorities to give credibility to their decarbonisation efforts, and the scientific community, which will have access to a set of quality measurement data, will also help to validate the satellite data.

As this approach to data synergy has not been used in France until now, AEROLAB SPACE is emerging as a national flagship project for climate change adaptation and mitigation.

Application site(s)

Grand Est Region (France)



  • Sentinel-5P (Tropomi, CH4, NO2, CO)
  • Sentinel-2 (Albedo)
  • OCO2 (CO2)


  • In situ data from AEROLAB: balloon, aero-drone, ground station, open data (OSM, emission proxy). Greenhouse gas profiles from weather balloons, EM27/SUN integrated columns, aircraft and measurement towers
  • CAMS data: GHG simulation (carbon dioxide CO2, carbon monoxide CO, methane CH4, nitrogen dioxide NO2, nitric oxide NO)
  • Weather, wind and humidity data

Results – Final products

AEROLAB SPACE will take the form of a digital platform displaying indicators for monitoring GHGs on a regional scale and dynamic maps with regular updates of GHG emissions in the Grand Est region.

Users will be able to select a period and area of interest and view the desired parameters and indicators.

The tool's functionalities include those of a decision-making tool: zoom, time series, map comparison, display of indicators, statistics, trends, and assessment through analytical tools.

AEROLAB : Powered directly by the ongoing AEROLAB project, AEROLAB SPACE will be accelerated thanks to Capgemini's industrial know-how for the implementation of the pilot demonstrator in the city of Reims. AEROLAB SPACE will be based on the expertise and technological building blocks already developed by Capgemini in previous projects (Algorithm Orchestrator, Space Digital Platform).

For information, AEROLAB was inaugurated in September 2021 at the Châlons en Champagne fair, and is in a demonstration phase with the recent installation of an ICOS tower (14/10/2021) and the deployment of a network of urban sensors in Reims for the measurement of GHG. In parallel, GHG measurement campaigns using drones and aircraft have been underway since June 2021. In the spring of 2022, a car instrumented for the measurement of nitrogen compounds nitrogen monoxide (NO), nitrogen dioxide (NO2), carbon dioxide (CO2), nitrous oxide (N2O), ozone (O3), carbon monoxide (CO), ammonia (NH3), methane (CH4) and water vapour (H2O) was put into service.
