IASI monthly O3 partial columns over European, Eastern US and Western US Mountains between 2008 and 2020

Mean monthly partial O3 columns between 2008 and 2020 retrieved from IASI over European (5-20°E,40-50°N), Eastern US (70-85°W,35-50°N) and Western US(100-125°W,30-50°N) Mountains. The data correspond to the lowermost troposphere (surface-3km), the lower free troposphere (3-6km), the upper free troposphere (6-9km), and the upper troposphere lowermost stratosphere (9-12km). These data have been used for ozone analysis (Putero et al., 2023) in the framework of the tropospheric ozone assessment report – phase 2 international initiative.
