Abstract:

Particles in the air absorb and scatter electromagnetic waves, causing transmission loss and image obscuration. The patterns of scattering and extinction are functions of wavelength, particle size, and particle number. In order to calculate the transmittance and extinction of multispectral target acquisition sensors, the number density and size distribution of particles along the target path need to be provided. Because the airborne particles are derived mainly from terrestrial sources, the distribution of airborne particles is critically controlled by the sediment transport processes. This study takes advantage of the extensive results and experience from sediment transport research in an attempt to develop an efficient algorithm of deriving the information of airborne particle distribution as a function of various environmental parameters....
