Temporal and Spatial Variations of Tropospheric Ozone over the Arctic
This study aims to address the temporal and spatial variations of tropospheric ozone over the Arctic from the 1980s to 2010s, using ozonesonde data and the Trajectory-mapped Ozonesonde dataset for the Stratosphere and Troposphere (TOST) data. In the lower and middle troposphere, ozone abundances are...
