Abstract

Understanding how greenhouse gases behave in the atmosphere is necessary to predict and prepare for climate change. We seek to develop a method to monitor greenhouse gas transport by measuring wind-induced Doppler shifts in atmospheric spectra. Our goal is to measure atmospheric winds by measuring the corresponding Doppler shifts of a water vapor absorption transition near 1367 nm. We have developed a frequency comb calibrated tunable laser spectrometer and an approach to simulate how variability in atmospheric conditions affects measurements. We measure shifts in the water vapor absorption transition in the lab, and then analyze the data and discuss our precision in taking measurements. We also build an apparatus for future outdoor measurements.
