Laboratory and field evaluation of a low-cost methane sensor and key environmental factors for sensor calibration.

ABSTRACT: Low-cost sensors enable finer-scale spatiotemporal measurements within the existing methane (CH₄) monitoring infrastructure and could help cities mitigate CH₄ emissions to meet their climate goals. While initial studies of low-cost CH₄ sensors have shown potential for effective CH₄ measurement at ambient concentrations, sensor deployment remains limited due to questions about interferences and calibration across environments and seasons. This study evaluates sensor performance across seasons with specific attention paid to the sensor's understudied carbon monoxide (CO) interferences and environmental dependencies through long-term ambient co-location in an urban environment. The sensor was first evaluated in a laboratory using chamber calibration
