We derive an effective coupling parameter for two-dimensional Yukawa systemsbased on the height of the first maximum of the pair distribution function. Twovariants -- one valid in the high-coupling range, the other for arbitrarycouplings of the liquid -- are derived. Comparison to previous approaches toYukawa coupling parameters shows that the present concept is more general andmore accurate.  Using, in addition, dynamical information contained in the velocityautocorrelation function, we outline a reference data method that can beemployed as a non-invasive measurement scheme of the plasma parameters -- thecoupling strength and the screening length. This approach requires only inputfrom a time-series of configuration snapshots and particle velocities with norecourse to additional information about the system. Our results should bedirectly applicable as a simple, yet reliable diagnostic method for a varietyof experiments, including dusty plasmas, colloidal suspensions and ions intraps, and can be employed to facilitate comparisons between experiments,theory and simulations.
