Comparison of Thermal-Optical Transmission and Thermal-Optical Reflectance Methods of Measurement of Organic and Elemental Carbon in Atmospheric Aerosol

Abstract

Abstract:

Organic carbon (OC) and elemental carbon (EC) in atmospheric aerosols play a major role in environment, climate and human health effects. At present, thermal-optical method is acknowledged to be a more mature method for measuring the OC and EC, which can be divided into two methods, thermal-optical transmission (TOT) method and thermal-optical reflectance (TOR) by the optical correction way. Theory of the two methods is almost the same, but the measuring results are different obviously. Therefore, a thermal-optical transmission and reflection simulating experiment platform are developed by deeply understanding the theory of thermal-optical method. Through contrast experiment, it is indicated that the reason leading to the obvious difference between the two methods is that TOR laser split come more early than TOT.

Key words: thermal-optical transmission, thermal-optical reflectance, organic carbon, elemental carbon, laser split
