Anthropogenic activities, mainly fossil fuel combustion, cement manufacturing, and land use change, have increased [...] gas emissions (IPCC, 2013). It additionally acts as a carbon sink. About 25% of the released anthropogenic CO2 was taken up by the ocean (Friedlingstein et al., 2019). As a consequence, the ocean is warming [...] altitude with a maximum at 20 to 25 km, however, ozone is also present in the troposphere due to anthropogenic activities. Nitrogen oxides NOx (NO, NO2) are also found in both layers. The main source of NOx
