Route de Fay-aux-Loges, Trainou 45470, France
Lat: 47.96°N, Lon: 2.11°E, Alt: 131 m above see level
Sampling heights: 5, 50, 100, 180 m above ground level
The Trainou tower station is dedicated to greenhouse gas measurements. It is located in the Orléans forest (47.96°N, 2.11°E, 131 meter above see level), about 15 km northeast of the city of Orléans (116 000 inhabitants), approximatly 100 km south of Paris. The station surroundings is mostly covered by forest (30 %) and agriculture fields (50 %) (INSEE 2008, National Institute of Statistics and Economic Studies, 2008). The Trainou station has been initiated in 2006 in the framework of the European projects CHIOTTO (Continuous HIgh-precisiOn Tall Tower Observations of greenhouse gases) and CarboEurope IP.
The site benefits from a tall telecommunication tower belonging to TdF (Télécommunication de France). The tall tower allows atmospheric measurements at 5, 50, 100 and 180 meters above ground level. The station has initially been designed for high precision and continuous measurements of CO2, CH4, N2O, SF6, CO and H2 at the four measurement levels of the tower. Since its initial installation, regular update has allowed to add in situ GHG proxy measurements such as Radon-222 (2009), 14CO2 integrated over 15 days (2008) or COS (2016-2020). SF6 and H2 measurements have been respectively stopped in 2013 and 2020.
In addition to the in situ measurements, total column abundances of CO2, CH4, CO and N2O are retrieved since 2009 in the framework of TCCON (Total Carbon Column Observing Network) network. The ground-based Fourier transform spectrometer (FTS) is managed by IUP Bremen (Germany).
A complete description of the in situ instrumentation and associated time series from 2006 to 2013 in given by Schmidt et al. 2014.
The Trainou station has become one of the major greenhouse gas measurements station in France and Europe. Year 2018 has been a hinge year for the station as it has been integrated to the ICOS (Integrated Carbon Observation System) network making it one of the only few European station being part of two major networks for GHG measurements: ICOS and TCCON.
In situ and continuous : CO2, CH4, N2O, CO and 222Rn
Integrated : 14CO2 (over 15 days)
Total column : CO2, CH4, N2O and CO
