Interactive comment on “Aerosol microphysical retrievals from Precision Filter Radiometer direct solar radiation measurements and comparison with AERONET” by S. Kazadzis et al

The authors present results of measurements with a precision filter radiometer and compare their results to collocated measurements carried out with an AERONET (CIMEL) sun photometer. The purpose of the study is to show that the measurements of the precision filter radiometer, which is used by the GAW aerosol network, can be used to extend the data available from AERONET sun photometers. The authors show aerosol optical depth and Angstrom exponents. Results for effective radius and volume concentration are derived with the linear estimation inversion technique (LE method) which has been published before by one of the coauthors of this publication. The authors derive effective radius and volume concentration from data taken with the filter
