Paper Abstract

A method based on the absorption of Chappuis band in the visible region has been developed in order to retrieve column ozone content together with aerosol optical depth by means of direct spectral irradiance measurements. Due to the great sensitivity in this spectral region of ozone to aerosol contribution and vice versa a careful supervised fitting using adequate windows is carried out. The fit is according to the Angstrom formula. Taking either the modeled aerosol optical thickness or the experimental one the aerosol size distribution is obtained by an inversion method. Preliminary results from March to July of 1995 are shown in the area of Valladolid, located in the center of the Castilla-Leon region, in Spain. The retrieved values of ozone content are according to the expected ones, but variations during this period are clearly manifested. Also aerosol optical depths for this period are monitored together with the aerosol characteristics.
