Abstract

Semiconducting metal oxide gas sensor arrays, when combined with temperature modulation, have demonstrated promising performance in laboratory tests for outdoor air-quality applications. However, their suitability for long-term field deployment across multiple seasons remains insufficiently validated. In this study, the system was deployed alongside an air-quality reference station over 17 months. The model for predicting NO2 and O3 achieved a normalized root-mean-square error of less than 8%, demon- strating robust multi-season outdoor performance.
