Accurate monitoring of trace gases requires high sensitivity, drift-free instruments. Dual frequency comb spectroscopy is a promising technique for kilometer-scale open-path monitoring of trace gases, owing to its low systematic uncertainty, high stability, and absorption-model-based calibration. I’ll talk about the basics of frequency combs, the recent development of robust portable combs at NIST, and the application of these tools for atmospheric trace gas monitoring, methane leak detection, and measurements in harsh environments.
