Short summary
We developed a new technique to measure air pollutants. This method can detect many gases, including volatile organic compounds and nitrogen oxide released by plants and human activities. We tested it in two locations and found it agreed well with standard instruments, while offering improved performance. Our results show this approach can provide broad and sensitive monitoring of air quality and chemical processes in the atmosphere.
