Correlation between the particulate matter (Pm10) mass concentrations and aerosol optical depth in Bucharest, Romania

摘要

The relationship between AOD (Aerosol Optical Depth) computed usingOPAC (Optical Properties of Aerosols and Clouds) software and AOD retrieved fromsatellite was examined, for their reciprocal validation. Then the similar relationshipbetween in situ measurements of PM10 mass concentrations near the ground and dailymean AOD values retrieved from satellite was inferred. The couples of data files fromthe three selected pollution monitoring stations from Bucharest area, during 2008"009were statistical analyzed and the correlation coefficients between AOD computed andthat from satellite on one hand and between PM10 and AOD on the other hand weredetermined. The correlation coefficients varied between 0.60 and 0.90, depending onthe type of station. The results have shown that the regression method can be used topredict the values of PM10 or AOD for a time period, knowing the relationship betweenthe two variables and values for one of them for another time period.
