Short summary
Long-term field testing across diverse climatic environments is conducted to identify the optimized calibration conditions for NO2, NO, CO and O3 electrochemical sensors. The results uncovered three factors that influence calibration performance: calibration period, concentration range and time averaging. We developed a comprehensive framework for the best sensor calibration practices, which serves as a valuable reference for calibrating various sensor types used in air quality monitoring.
