Abstract
During the last few years, scientists have become increasingly concerned about air quality. Particularly in large cities and industrialised areas, air quality is affected by pollution from natural and anthropogenic sources and this has a significant impact on human health. Continuous monitoring of air quality is an important step in investigating the causes and reducing pollution. In this paper, we propose a new autonomous multi-rotor aerial platform that can be used to perform real-time monitoring of air quality in large cities. The air quality monitoring system is able to cover large areas, with high spatial resolution, even above average buildings, while being relatively low cost. We evaluate the proposed system in several locations throughout a metropolitan city, during different seasons and generate fine-grained heat-maps that display the level of pollution of specific areas based on different altitudes.

The data collection was made throughout the autumn and winter, when temperatures varied from −5 to 10 ◦C and the humidity fluctuated depending on the weather conditions, with some of the measurements taken during snowy days
Summary
Pollution has gradually become an important factor that affects the lifestyle and health of individuals, increasing morbidity and mortality [1]. PM2.5 (fine particulate matter) concentration in Hotan, in September 2021, was 15 times the maximum value recommended by the World Health Organisation (WHO) and the air pollution level is considered hazardous [5]. Another factor that affects air quality in China is the high concentration of smog that originates from the coal burning factories that fuels China’s highly industrialised economy, but affects the health of individuals living within the vicinity
