WebThe proposed 4-angle BRDF normalization model demonstrated good potential for normalization in the longer wavelength bands but less potential for normalization in the coastal aerosol and blue bands. This can be explained by the fact that these bands are more sensitive to changes in atmospheric characteristics than direct changes in solar position. WebClimate change studies require consistent, long time series, surface reflectance data. The characterization of the bidirectional reflectance distribution function (BRDF) is important for normalizing the solar radiation reflected from the earth's surface. We evaluated four BRDF models to identify the preferred approach to the normalization of multiyear National …
