The dataset corresponds to an analysis of a premixed methane-air flame undergoing side-wall quenching in a fully-develped turbulent channel flow. Thereby, the unresolved fluctuations of the reactive scalars are investigated that need to be modeled in turbulent-chemistry interaction closure.

Furthermore, data of an a-priori analysis of two presumed probability density function models are presented.
