Understanding the vertical profile of air pollutants is crucial for comprehending the formation and transport of air pollution.

Helicopters serve as an effective tool for in-situ measurements of air quality. To enhance regional studies on pollution transport and formation mechanisms in the Greater Bay Area (GBA), Sapiens has collaborated in a 3D Air Quality Monitoring Program organized by the Hong Kong Environmental Protection Department (HKEPD), the Government Flying Service (GFS), the GBA Environmental Laboratory and the Hong Kong University of Science and Technology (HKUST). This initiative aims to investigate ozone pollution in the GBA, utilizing the GFS helicopter fleet for air quality model validation.
