内容 研究概要:Based on the property of vegetation reflectance spectra in the range from near-ultraviolet to near-infrared and the sensitivity of outgoing radiance to the reflectance and aerosol optical depth, a so-called iteration-correlation inversion algorithm is proposed to simultaneously derive the reflectance and aerosol optical depth. According to numerical inversion simulations, effects of the measurement error in radiance, the error in aerosol imaginary index and the vegetation ununiform on inversion results are analyzed. As shown in inversion simulations, as the error in the imaginary index is within 0.01. standard deviations of solutions of the reflectance and the optical depth for 14 wavelength channels are less than 0.063 and 0.023. and under 2% error of radiance, they are less than 0.023 and 0.0056. respectively, showing a satisfactory accuracy.
