Abstract
The observations of marine boundary layer NO2 vertical column density (VCD) over the yellow sea near Qingdao by ship-borne Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) were conducted with a Chinese oceanographic research vessel, XYH 08, during an offshore observation campaign, from 13 September 2015 to 18 September 2015. During the observation campaign, the ship-borne MAX-DOAS system made anchor point measurements in different sea areas including Qingdao coastal waters, the Yellow Sea, the Jiaozhou Bay and the Yangkou Bay area. Measurements results of anchor point measurements are presented in this paper. The air mass factor (AMF) errors caused by the vibration of the ship are also studied in this paper. Under good sea conditions on 14 September, the AMF errors of NO2 measurements caused by the ship vibration were evaluated to be less than 5%. By combining geometric character of monitoring area and weather condition, it can be concluded from the Jiaozhou Bay and the Yellow Sea measurement results that the meteorological conditions cause significant influence on local boundary layer NO2 content. The comparison of different anchor point measurements showed that the Jiaozhou Bay sea area had much more NO2 content than Yangkou sea area because the Jiaozhou Bay sea area is located in Qingdao urban area with surrounding NO2 contamination.
