Regression Approach To Analyzing The Informativity And Interpretation Of Aerosol Optical Measurements
Published 2009 · Chemistry
A regression approach is proposed for planning aerosol optical experiments and for estimating the potential accuracy of the derived microphysical parameters of atmospheric aerosols taking the features of the apparatus and the available a priori information into account. This method is used to evaluate the informativity of polarization spectronephelometer measurements with respect to the microphysical parameters of continental aerosols. The problem of choosing the most informative aerosol optical characteristics with respect to the mass concentrations of the PM2.5 and PM10 respirable fractions is examined and regression equations are derived for determining these concentrations from lidar probe data at wavelengths of 0.355 and 1.064 μm, as well as from reference measurements at 0.37 and 0.98 μm. The theoretical results obtained here are compared with AERONET data.
