Description
The Puy de Dôme station is operated by CNRS-INSU and University Clermont Auvergne (UCA). Puy de Dôme is the highest point of the Chaîne des Puys, which comprises 80 volcanoes aligned north to south on a 3 to 5 km wide strip of land, over 45 km in length. It is surrounded by a protected area where fields and forests are predominant. The city of Clermont-Ferrand (150 000 inhabitants) is located 16 km east of the station at 396m a.s.l. Previous work at the station shows that the influence of the city on the Puy de Dôme measurements remains undetected and that the station is representative of the regional background (Asmi et al. 2011 ; Henne et al., 2010). During winter/spring time and all year during nighttime, LIDAR measurements show that the station lies in the free troposphere/residual layer and air masses are exempt from the influence of local pollution.
The atmospheric research station hosts different analyzers for long-term atmospheric measurements of GHG, CO, O3, aerosols, radon-222, clouds microphysics and radionuclides. The station has international labeling EMEP (European Monitoring and Evaluation Programme), GAW, and is part of the European ACTRIS and ICOS measurement networks. The station has been labelled in ICOS-ERIC on 31 may 2018.
Atmospheric CO2 mole fractions have been continuously measured at PUY since 2000. NDIR analyzer was used from 2000, and then replaced by a CRDS instrument in 2011which measures both CO2 and CH4. CO2, CH4, N2O and SF6 have also been measured from 2010 to 2015 with a gas chromatograph system (Lopez et al., 2015).
Measured species
In situ and continuous: CO2, CH4, N2O, CO and 222Rn
