Vaisala takes on Chinese air quality

Air quality is a growing health problem that especially impacts people in densely populated megacities.

Finnish Vaisala aims to improve the understanding of air quality in China with a new groundbreaking concept.

Over the next two years, Vaisala will build a dense air quality observation network in the metropolis of Nanjing and the Yangtze River Delta. The air quality services and applications developed in the project will offer tools to better understand the complex air quality environment in China.

“Being able to measure pollutant concentrations in a dense network and applying modern modelling tools to this data make it possible to deliver air quality forecasts, which are far more meaningful and relevant for the citizens than those currently,” says Jarkko Sairanen, EVP for the Weather Business Area at Vaisala.

The network will also be complemented with vertical atmospheric Vaisala LIDAR (Light Detection and Ranging) profiling devices. Therefore, another important outcome of the project is the concept for a next generation air quality station that is capable of adding a vertical component to modelling.

“With this vertical component we are able to provide a 3D model of the local air quality, helping the customer to understand the local air quality more profoundly and thus make better informed decisions,” says Sairanen.

Vaisala is carrying out the project together with the University of Helsinki, the Finnish Meteorological Institute and later also Chinese partners. The collaborative research and demonstration environment will advance several areas in ambient air quality monitoring.
