Low-cost PM monitors as an opportunity to increase the spatiotemporal resolution of measurements of air quality

To care for air in Poland and in the world, its quality is monitored. Owing to the obtained data, it is possible to develop appropriate plans of air quality improvement. Unfortunately, the number of professional measuring devices is usually insufficient. For example, in the capital of Poland, Warsaw, in the area of 517 km(2) data on concentrations of pollutants in the air within the State Environmental Monitoring, provide only 8 automatic stations. The paper presents the concept of using low-cost PM measuring devices to increase the spatiotemporal resolution of air quality measurements supplementing the network of reference devices. It is presented a prototype network of such devices installed in Nowy Sacz, as well as results of measurements obtained by its using. (C) 2017 The Authors. Published by Elsevier Ltd.
