Trainou Observatory - Panel Board

The Trainou Tower station (TRN) is located in the “Centre” region in France (47°57’53”N, 2°06’45”E, 131 m above sea level) at a 200 m transmitter mast owned by TDF. We equipped four sampling levels on this tower at 5 m, 50 m, 100 m and 180 m above ground level. Trainou station is about 15 km northeast of the city of Orléans (116000 habitants) and about 100 km south of Paris. Five small villages ( less than 2000 inhabitants ) are located nearby the station. In the surrounding of the station, the area is covered by forest (30%) and agriculture fields (50%). Greenhouse gases measurements have been started at Trainou in 2007 in the frame of the European projects CHIOTTO (Continuous HIgh-precisiOn Tall Tower Observations of greenhouse gases, and CarboEurope IP ( The in-situ measurements at 4 levels of Trainou Tower are completed by regular airborne measurements between 100 m and 3000 m altitude close to the tower. IUP Bremen installed at trainou in the frame of the TCCON (Total Carbon Column Observing) network a ground based FTS to analyse the column abundances of CO2, CH4, N2O .
