Abstract: This paper presents a practical method for the development of spectral reflectance libraries under sub-optimal sky conditions.\  Although there are commercially available spectrometers which simultaneously measure both downwelling and upwelling radiance to mitigate the impact of sub-optimal sky conditions, these spectrometers only record in the visible and near infra-red.\  There are presently no commercially available spectrometers with this capability that can record the visible through short-wave infra-red.\  This paper presents a practical method of recording and processing data using coordinated measurements from two full-range spectrometers and discusses potential pitfalls and solutions required to achieve accurate reflectance spectra.\  Results demonstrate that high-quality spectral reflectance libraries can be developed with this approach.
