The data set comprises full cavity ring-down spectra and absorption coefficients obtained from on/off-resonance measurements, in order to determine the spatial distribution of H2O2 in the cold atmospheric pressure plasma jet kINPen-sci. Therefore, the plasma jet was operated with 3 slm Ar and 3000 ppm water, and was equipped with a gas curtain of 5 slm O2. To determine the effective absorption length, the H2O2 absorption was measured in radial direction. These radial fits had a Gaussian-like shape.

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 data set comprises the spatial distributions of H and O atoms in the cold atmospheric pressure plasma jet kINPen-sci. The data was obtained by means of picosecond two-photon absorption laser induced fluorescence spectroscopy (ps-TALIF) and numerical simulations.
