Using Sun Fits images for calculation of terrestrial aerosol optical depth (AOD) and Ångström turbidity parameters in countryside of Kufa district

Abstract

Since there are no previous studies conducted for calculating Kufa turbidity parameters considering that the urban pollutions is less than that of the Kufa city. For this The prior location of the Faculty of science telescope was chosen to make such observation using a 60 mm solar telescope Coronado of Hα filter equipped with CCD DSI III pro connected to laptop computer . Sun Fits images were captured under a clear sky as well as dusty conditions. Two types of images were classified, one in the clear sky and the other in dusty weather. Matlab code was used to estimate sun intensities in order to calculate aerosol optical depth and Ångström turbidity parameters from sun images. These values are expressing the normality behavior with nearer places in territorial region.
