N2 - The problems associated with simple models for terrestrial and planetary surface reflectance are discussed and the value of using more rigorous expressions that properly describe the effects of sub-pixel shadowing at low solar zenith angles is emphasised. The use of such expressions will improve the accuracy of theoretical reflectance estimates and could provide information useful in geological mapping, geomorphology, vegetation classification, climatology and micrometeorology.
