Abstract
A procedure is formulated to investigate the sensitivity of surface reflectances retrieved from satellite sensor data to uncertainties in aerosol optical properties. Aerosol optical characteristics encompassed in the study include the Junge parameter (i.e., spectral dependence), the imaginary part of the refractive index (i.e., aerosol absorption), and the aerosol optical depth. Key results for a wavelength of 0.550 micrometers are presented graphically in terms of accuracy requirements on the aerosol property under consideration for a 5 uncertainty in predicted surface reflectance.
