Description
Summary:Field and laboratory radiometers have long been used to characterize the multiangle reflectance properties of homogeneous surface targets. Within the last few years space-based multiangle spectroradiometers have been deployed, including the Along-Track Scanning Radiometer-2 (ATSR), the Polarization and Directionality of the Earth's Reflectances (POLDER) instrument, and the Multiangle Imaging SpectroRadiometer (MISR). Other scanning instruments, such as the Moderate Resolution Imaging Spectrometer (MODIS) make use of successive passes to build up multiangle observations. With global monitoring from space, as well as the continuation of traditional observations in the field, advances are being made in research and applications which use these data. There comes a need, with this growth, to standardize reflectance terminology. Success in this endeavor will ensure the integrity of the data products, and facilitate the intercomparison of results. This paper reviews the reflectance terminology that is currently in use by the remote sensing community, including bidirectional reflectance distribution function, bidirectional reflectance factor, hemispherical-directional reflectance factor, directional-hemispherical reflectance, hemispherical-directional reflectance, and bihemispherical reflectance (albedo).
