Analysis of PM10 Concentration Time Series and Climate Factor in Hangzhou 2004

摘要

The density of absorbable particulate matter (PM10) is the most important contamination index for air quality monitoring. This article analyzed the temporal variation characteristics of PM10 and its climate influencing factors. We employed wavelet analysis method to extract the overall tendency of annual variation. Likewise, the relationship between PM10 density and meteorological factor was established by correlation analysis. Moreover, a summary of the yearly temporal characteristic of PM10, as well as its daily characteristic in Hangzhou, was provided. A summary of the factors that influence its climate is provided.
