The comparison of the darkest pixel and empirical line atmospheric correction methods to retrieve aerosol optical thickness using the radiative transfer equations

摘要: This paper presents a comparison of the darkest pixel (DP) and empirical line (EL) atmospheric correction methods in order to examine their effectiveness retrieve aerosol optical thickness (AOT) using radiative transfer (RT) equations. Research has found that DP EL are two simplest most effective of atmospheric correction; however, which is more in deriving accurate AOT values remains an open question. The accuracy were examined pseudo-invariant targets urban area Limassol Cyprus, by reflectance before and after correction. Eleven Landsat 5 7 satellite images were atmospherically corrected both the methods. following method used in the equation derive values. Following, assessment was conducted comparing the in-situ as measured from sun photometers with derived RT equations order to determine for retrieving AOT. study atmospheric correction provided accurate than method.
