Sky reflectance Rsky(l) is used to correct in situ reflectance measurements in the remote detection of water\ud colour. We analysed the directional and spectral variability in Rsky(l) due to adjacency effects against\ud an atmospheric radiance model. The analysis is based\ud on one year of semi-continuous Rsky(l) observations\ud that were recorded in two azimuth directions. Adjacency\ud effects contributed to Rsky(l) dependent on season and viewing angle, and predominantly in the near-infrared (NIR). For our test area, adjacency effects spectrally resembled a generic vegetation spectrum. The adjacency effect was weakly dependent on the magnitude of Rayleigh- and aerosol-scattered radiance. Reflectance differed between viewing directions 5.4 +/- 6.3% for adjacency effects and 21.0 +/- 19.8% for Rayleigh- and aerosol-scattered Rsky(l), in the NIR. It is discussed under which conditions in situ water reflectance observations require dedicated correction for adjacency effects. We provide an open source implementation of our method to aid identification of such conditions. Copyright 2017 Optical Society of America.
