Short summary
Our study examines a lesser-known atmospheric feature, the Asian Tropopause Aerosol Layer, located high above the Earth. We investigated how different aerosols, such as sulfates, nitrates, and pollutants, influence the exchange of heat between the atmosphere and its surroundings. The results show that these particles can alter temperature patterns, especially during the Asian summer monsoon. This research improves our understanding of how human activities may affect regional climate.
