Abstract
An experimental campaign was carried out at Central Geophysical Laboratory at Belsk (Poland) in October 2007. Three sun photometers: Cimel CE-318, Prede POM-01L and Microtops II were used to obtain the atmospheric aerosol optical characteristics. Cimel CE-318 and Prede POM-01L are automatic sun-tracking devices common in the world networks for aerosol investigations AERONET and SKYNET. Microtops II is a hand-held manual device often used in field experiments because of its mobility. The results obtained show similar behavior of the aerosol optical depth variations and close values obtained by the three devices at the common wavelengths over rural area. The Microtops II readings are between the readings of the other two sun photometers. The experiment carried out is helpful and shows that the Microtops II sun photometer provides comparable results to these obtained by the Cimel CE-318 and Prede POM-01L sun photometers and potential of using Microtops II for measurement over an urban and rural area.
