Assessing a low-cost methane sensor quantification system for use in complex rural and urban environments.

摘要: Abstract. Low-cost sensors have the potential to facilitate exploration of air quality issues on new temporal and spatial scales. Here we evaluate a low-cost sensor quantification system for methane through its use in two different deployments. The first was 1-month deployment along Colorado Front Range included sites near active oil gas operations Denver-Julesburg basin. second an urban Los Angeles neighborhood, subject complex mixtures pollution sources including operations. Given role as potent greenhouse gas, methods detecting monitoring may aid protecting human environmental health. In this paper, assess number linear calibration models used convert raw signals into ppm concentration values. We also examine choices that can be made during data processing explore cross sensitivities impact type. results illustrate accuracy Figaro TGS 2600 when is quantified from using techniques described. demonstrate value these tools examining trends events small scales well their ability characterize area – highlighting provide preliminary inform more targeted measurements or supplement existing networks.
