Abstract The complexity of forest canopies and the variability of atmospheric conditions necessitate the normalization or standardization of satellite imagery. Standardized reflectance images were produced by using atmospheric correction in a simplified procedure. The atmospheric parameters at overpass time were evaluated by using interpolation among local meteorological records. The path radiance derived from the visual range is adjusted by the dark pixels in the image data. The normalized reflectance images were enhanced with linear or nonlinear transformation for storage. A set of four date subscenes were used as examples to illustrate the good correspondence of reflectance results from quite different atmospheric conditions.
