摘要

Abstract

The concentrations of the gases ¹²CO₂, ¹³CO₂, СН₄, and Н₂О and the trends of Earth degassing under changing atmospheric pressure were analyzed remotely for the first time using a differential absorption lidar. To reduce the influence of external meteorological factors, the sensing was carried out in a dead-end tunnel of the Baksan Neutrino Observatory of the Institute for Nuclear Research, Russian Academy of Sciences.
