Abstract
Trace atmospheric gases (TAGs) emitted by the Earth's water surface significantly impact the chemical processes in the atmosphere, weather formation, and the global climate change. The main TAGs emitted from the ocean surface and wetlands are described and analyzed. The laser absorption spectroscopy technique for local/remote gas-analysis suitable for detection of several TAGs is considered, including cavity-ring down spectroscopy and optical-acoustic 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 considered, as well as examples of their implementations.
