Abstract

Summary

Assessment of atmospheric carbon monoxide (CO) vertical column density (measured in 102 mol/m2) over the Crimean Peninsula (Ukraine) was conducted using imagery extracted data from the TROPOMI instrument on the Sentinel-5 Precursor satellite for the period from January 2019 to July 2023. Daily satellite observation data was monthly and yearly averaged with a step of 7×7 km2 at the grid nodes and also at NUTS 3 administrative level boundaries. In 2019–2022 over the Crimean Peninsula averaged of the average content of atmospheric CO vertical column density was 3.3±0.2 × 102 mol/m2. The minimum content of this gas is typical for the mountainous regions of the Crimea, about 2.7+0.2 × 102 mol/m2. The maximum CO vertical column density content is typical for coastal and junction with the mainland areas and amounts to 3.6±0.2 × 102 mol/m2. The content of CO in the atmosphere over the steppe part of Crimea is close to average values. Most likely, the content of the CO vertical column density in 2022 has dropped to 2.9±0.2 × 102 mol/m2 due to the decrease in industrial and agricultural production, a decrease in tourist flows, and a decrease in the contingent of russian enemy troops that moved to the south of Ukraine. In the summer of 2023, there was a certain increase in the concentration of CO in the atmosphere, which is associated with natural processes, but the most likely dominant factors were the transfer of heavy enemy military equipment and fires in the territory of the Crimean Peninsula.
