Two OA-ICOS devices, connected in series and sharing a suite of calibration and reference gases, have been employed to make continuous measurements of atmospheric CO2, CH4, N2O and CO concentrations. The data are calibrated by performing a linear regression upon the weekly measurements of three calibration (tied to the latest NOAA calibration scales) cylinders. The quality control procedure incorporates regular measurements of a dedicated reference cylinder (Target Tank), carefully calibrated at Max-Planck Institute for Biogeochemistry (Germany).","keywords":"","status":"","publicationState":"","identifier_set":[],"observationCollection":[],"parentProject":null,"subProject":[],"responsiblepartyinfo_set":[]}
