Accurate measurements of co 2 mole fraction in the atmospheric surface layer by an affordable instrumentation
International audience We aimed to assess the feasibility of an affordable instrumentation, based on a non-disper-sive infrared analyser, to obtain atmospheric CO 2 mole fraction data for background CO 2 measurements from a flux tower site in southern Finland. The measurement period was November 200...
