Remote sensing distortions

Satellite and airborne remote-sensing data are subject to large distortions that could substantially reduce their usefulness. There are three main distortion factors that could interfere with the collection of spectroscopic imaging data from space or airborne instruments for agricultural applications9,10 ... 

The sun, an important factor to take into account in remote sensing using spectroscopic imaging instruments. The passive optical system and the atmosphere through which the energy passes, both from the sun to the earth s surface and back to the instrument, interferes with the data collected. Atmospheric distortions include the effect of scattered dry air molecules (haze) and absorption by air molecules.
