The remote sensing community generally attributes all atmospheric blur in satellite imagery to aerosol forward scatter of light at small angles. Many in the propagation community attribute atmospheric blur solely to turbulence. It is our view that atmospheric blur must be approached from a broad system engineering point of view encompassing both turbulence and aerosol blur, as well as effects of atmospheric absorption and contrast reduction caused by atmospheric path radiance. We show examples of the problems caused by ignoring aerosol blur in the propagation community and by ignoring turbulence blur in the remote sensing community. In the latter case it is shown that image restoration from atmospheric blur in satellite imagery should involve correction for both aerosol and turbulence blur in order to obtain best results. The examples shown use Landsat TM imagery of Senegal under various atmospheric dust.
