Black Carbon Aerosol (BC) has recently been identified as a factor, second only to carbon dioxide, resulting in global climate change. Black carbon aerosol generates from the incomplete combustion of fossils and biomass fuels, such as motor vehicle exhaust, thermal power, forest fires and so on. Black carbon aerosols can strongly absorb natural light and have a significant effect on solar radiation balance. Unlike the long-term stability of carbon dioxide, the existence cycle of black carbon aerosol in the atmosphere is only a few weeks, and the regional effect is significant. Therefore, continuously monitoring mass concentration of black carbon aerosol is of great significance.
