The BRDF of any material may be obtained using either broadband or discrete wavelength sources, eg. solar spectral distribution simulators or lasers. Presently, there exists some discrepancy in the interpreta-tion and comparison of measurements made with these two sources. A reconciliatory methodology is presented in lieu of the current disarray of attempts to correlate scatter information obtained with lasers with that obtained using solar simulators. A technique is offered which is capable of rendering the few BRDF data obtained at discrete laser lines as a viable source for comparison to solar simulators. The solar spectral distribution (at air mass zero) was approximated analytically and used as a weighting function for the spectral BRDF of several generic types of scattering surfaces including white and black diffusers and specular samples; this defines the analytic solar BRDF. By conducting a solar spectral distribution weighting on the BRDF data obtained at various laser wavelengths, the resulting (calculated) solar weighted BRDF
