From May 2018 to May 2019, together with Fudan University and Zhenyi aviation, we participated in the UAV air pollution vertical monitoring project of Shanghai Pudong New Area Environmental Protection and city appearance Bureau. This project systematically and comprehensively observed the vertical and horizontal changes of air pollutant concentration in Pudong near surface atmospheric boundary layer (0-1000m), analyzed the distribution law and generation and consumption mechanism of pollution, especially the interaction mechanism between vertical and horizontal levels. The research object is closely related to human life in the 0-1000m vertical space for air pollution observation (PM2.5, ozone, nitrogen oxides, black carbon and other pollutants) and data acquisition. It explores the horizontal and vertical distribution and variation characteristics of fine particles and their precursors under typical weather conditions (such as before and after haze), analyzes the components and variation characteristics of pollutants at different heights, reveals the transport process of pollutants, and analyzes the causes of pollution and the source of fine particles. At the same time, it also provides technical support for modeling, environmental assessment and prediction
