Field investigations on spectral hemispherical reflectances of typical natural and artificial surfaces in urban and rural areas (environmental surfaces) have been performed for solar radiation in the wavelength range from 0.4 to 1.7 μm. Reflectance measurements were carried out accurately by a newly designed compact field spectrometer using an optical fiber and an integrating sphere with a wide view angle, regardless of the angular distribution of the incident and reflected solar radiation.
