Short summary
The tropical tropopause layer (TTL) is a crucial region where the troposphere transitions into the stratosphere, influencing air mass transport. This study examines temperature trends in the TTL and lower stratosphere using data from weather balloons, satellites and reanalysis datasets. We found cooling trends in the TTL from 1980 to 2001, followed by warming from 2002 to 2023. These shifts are linked to changes in atmospheric circulation and impact water vapour transport into the stratosphere.
