Investigating the Causes of Excessive Ozone Level in Tibet

Sector：Harsh Environments

Location：Tibet, China

In recent years, Tibet faced a significant challenge from excessive ozone pollution. After calibrating the local national monitoring stations, the Shanghai Environmental Monitoring Center collaborated with the Tibet Environmental Monitoring Station to deploy a network of advanced micro air monitoring stations MAS Odour Plus from Sapiens. These stations provided comprehensive real-time data on a range of key pollutants, including PM2.5 PM10, SO2, NO NO2, O3, and TVOC. By analyzing the monitoring data, the team was able to establish a preliminary understanding of the connections between local oz
