AirQino stations resulted to be a robust tool for investigating air quality dynamics at a higher spatial and time-scales, providing further information compared to those provided by the sole reference station. These stations, installed over several key areas within a small municipality characterized by atmospheric pollutants, were able to capture air pollutant dynamics continuously, creating an efficient network of low-cost �supplementing� air quality stations. In respect of the whole dataset collected. Also, calibration and validation procedures at six months' distance confirmed the robustness of the sensors at maintaining good quality standards along the time
