Insights#
Monthly National Pollution#
Addis Ababa gets more polluted towards the end of the year in the winters. The summer months are the least polluted with NO2. This is an expected trend because pollution stays in the air for longer in the winters.This also results in higher particulate matter during the winters. However, the average value per year peaked in 2021 and fell after that. 2019 winter was also unexpectedly less polluted. The reasons for the peak in 2021 and dip in 2019 are yet unknown.
The northeastern parts of Addis are the most polluted compared to the rest across years. COVID years were unexepctedly more polluted than others.
