The Ar(³P₂) metastable density in the effluent of the cold atmospheric pressure plasma jet kINPen-sci was investigated as a function of the feed gas humidity, the gas curtain composition, and the distance from the nozzle by means of laser atomic absorption spectroscopy. The data set comprises the axial distributions of the Ar metastables as a function of these parameters.

The provided data describe the discharge current in DBD obtained by fluid modelling using different values of for the secondary electron emission coefficient γ and and the relative permittivity of the dielectric barrier εr in comparison with the measured current at a pressure of 100 mbar and an applied voltage amplitude of 1.8 kV. Furthermore, the dissipated power obtained by model calculations for different values of γ and εr together with the measured power in dependence on the pressure is given.
