Abstract
The effects of climate change on the structure of the planetary boundary layer are understudied compared to other aspects of the Earth system. To address this, 25 years of planetary boundary layer (PBL) observations from the Integrated Global Radiosonde Archive are examined to determine if the Planetary Boundary Layer (PBL) has been impacted by the changing climate. Stations are selected from each continent and several oceans to incorporate Earth’s diverse climate regimes. PBL depth, mean-layer temperature, humidity, lapse rate, and wind shear are examined for climate signals during the 1995-2020 period. Results will be examined for both global and regional trends. Potential modification of PBL depth by climate change would impact various processes such as cloud formation, precipitation, and pollution transport.
