Short summary

We analysed 30 years of measurements of total ozone and atmospheric particles above Slovakia to understand how human activities and climate change affect the air and the upper atmosphere. Our results show that air pollution by particles has clearly decreased, mainly due to lower emissions, while total ozone levels show signs of slow recovery. The rising height of the tropopause, linked to climate change, was found to influence ozone amounts in opposite ways.
