Short summary
The ATC automatically processes atmospheric greenhouse gases mole fractions of data sent daily by the ICOS network, this includes calibration and water vapor corrections. Data are stored in a database which has been developed with an emphasis on traceability. Instrument calibration and manual quality control lead to automatic revaluation of the mole fractions calculated in near-real time. Calibration corrections avoid artificial gradients between sites that could lead to error in flux estimates.
