The OSUC is taking part in a campaign to measure greenhouse gas flows (GHG - CO2 and CH4) using a drone, carried out last July on the La Guette peat bog (Cher) as part of the “Terra Forma” research program, coordinated by the CNRS, financed by the Programme d'Investissement d'Avenir (Equipex+/PIA3) and managed by the Agence Nationale de la Recherche.
