Urbanization As cities grow, the number of people subjected to the environmental conditions in urban areas continues to grow. On the other hand, the concentration of population, traffic, and industrial processes brings on changes in weather and environmental conditions, such as air quality. Air pollution is a threat to the health and well-being of people. Vaisala’s response to urbanization Vaisala provides reliable instruments, systems, and digital solutions to measure air quality and road weather as well as urban weather and microclimates. This helps smart cities to overcome their challenges with urbanization and make informed decisions regarding sustainability, economic growth, safety, and well-being. As industrial automation evolves, we offer diverse and advanced measurement technologies needed in buildings as well as industrial environments and processes that require precise and constant monitoring. Such environments include, for example, smart buildings, subway networks, industrial hubs, and large manufacturing facilities.
