Observation and Analysis of Atmospheric Aerosol Optical Properties in Spring of Tianjin Coastland in 2014

Abstract

Abstract:

Aerosol optical properties are important for climate, environment and satellite remote sensing. The aerosol optical data of Tianjin coastal area from March to May in 2014 are measured by using the CE317 Solar Photometer, and further analyzed. The results show that aerosol optical depth (AOD) spectra are basically accord with Angstrom relationship. There are three basic types of AOD daily variations, which are rising type, stationary type and declining type. The mean value of 440 nm AOD in spring is 0.776, the Angstrom exponent α is 1.011, and the Angstrom turbidity coefficient β is 0.344. The results are compared with the Qingdao area in the Yellow Sea coastland, which shows the regional characteristics of aerosol optical properties.

Key words: aerosol optical depth, Angstrom exponent, turbidity coefficient, Tianjin coastland
