Jomo Kenyatta University Of Agriculture And Technology ALP 2206: Remote Sensing 1 Interaction at the atmosphere By P. K. Wanyoike Energy recorded by remote sensor • Radiated (by sun) • Propagates through vacuum of space at speed of light • Interacts with the earths atmosphere • Interacts with the earths surface • Interacts with the earths atmosphere again • Finally reaches the remote sensor and interacts with various optical systems, filters, film emulsion, or detectors Interaction at the atmosphere • The interaction of EMR with the atmosphere is important to remote sensing for two main reasons. • First, information carried by EMR reflected/ emitted by the earth’s surface is modified while traversing through the atmosphere. • Second, the interaction of EMR with the atmosphere can be used to obtain useful information about the atmosphere itself. • The atmospheric constituents scatter and absorb the radiation modulating the radiation reflected from the target by attenuating it, changing its spatial distribution and introducing into field of view radiation from sunlight scattered in the atmosphere and some of the energy reflected from nearby ground area. • Both scattering and absorption vary in their effect from one part of the spectrum to the other. • The solar energy is subjected to modification by several physical processes as it passes the atmosphere, viz. – 1) Scattering; 2) Absorption, and 3) Refraction Energy interaction with the Atmosph ...
