英文摘要	The rectifier effect refers to the exchange of CO2 near the boundary layer of the atmosphere. This effect is an important part of the carbon cycle because it affects the vertical distribution of CO2 and indirectly affects global CO2 distribution. However, the intensity of this effect is difficult to measure directly. A differential absorption LiDAR (DIAL) system can observe the rectifier effect because this device can accurately measure planetary boundary layer height (PBLH) and CO2 profile concentration (Quan et al., 2014; Guo et al., 2016). Accordingly, we conducted experiments in Huainan, China using a DIAL system for CO2 detection developed by our group. We selected two cases, namely, summer and winter, for the analysis. Firstly, we calculated CO2 profile, average CO2 concentration and PBLH. Secondly, we analysed the rectifier effect. Results showed a negative correlation between PBLH and the rectifier effect. Simultaneously, we observed a special phenomenon in which CO2 concentration is lower near the ground than in high altitudes. This phenomenon may be explained by the activities of plants. © 2019 Elsevier Ltd
