Abstract:
An investigation to determine the correlation of atmospheric amounts of SO2 and NO2 between columnar measurements from the ground and ground point determinations has been performed. The experimental data have been obtained from a Brewer spectrophotometer for columnar measurements and standard analytical techniques for ground measurements.The results show that the Brewer can give a correct indication of the trend of these pollutants on a monthly averaged basis. The possibility of deducing the mixing layer depth from the measured data has also been investigated but the results obtained are not conclusive due to the lack of an accurate experimental verification.
