Abstract
We present the results of studying variations in the concentrations of the CO and H2O atmospheric constituents over the Baikal Natural Territory from the long-term (2010–2021) data of the MLS Aura satellite measurements. The data were analyzed at the stratospheric heights for pressure levels within 215–10 hPa (~11–32 km) for the locations of Khorinsk (52.17° N, 109.77° E) and Zhigalovo (54.81° N, 105.15° E). We obtained averaged seasonal variations in the concentrations of the analyzed components for each pressure level under day and night conditions for the 2010-2020 period. Comparison of the obtained results with the behavior of the concentrations of atmospheric constituents in 2021 revealed an increased CO concentration for Khorinsk in July–August 2021, when increased smoke from forest fires was observed in the analyzed region.
