Differential absorption lidar system employed for background atomic mercury vertical profiling in South China

In English

Författare

Summary, in English

A differential absorption lidar (DIAL) system based on a Nd:YAG laser pumped narrow-band dye laser is developed and employed to monitor the atmospheric background concentration of atomic mercury in Guangzhou, South China. Atmospheric oxygen is also studied by using neighboring wavelengths to the mercury absorption line (253.7 nm), and is used to verify the operation of the DIAL system. A 24-hour continuous monitoring of background mercury concentration is performed and the average atomic mercury concentration below 330 m is between 5 ng/m(3) and 12 ng/m(3). (C) 2013 Elsevier Ltd.
