Trace atmospheric gases (TAGs) emitted by the Earth’s water surface significantly impact the chemical processes in the atmosphere, weather, and global climate change. In the work, key TAGs emitted from the ocean surface and wetlands are analyzed. The laser absorption spectroscopy techniques for local/remote gas analysis suitable for detection of several TAGs are considered, including cavity ring-down spectroscopy and photoacoustic spectroscopy. Approaches to the development of laser absorption spectroscopy tools for the control of a large number of TAGs using an optical parametric oscillator as a tunable laser source are described, as well as examples of their implementation.
