Enhancement of Arctic surface ozone during the 2020–2021 winter associated with the sudden stratospheric warming
Abstract Surface ozone is an important pollutant causing damage to human health and ecosystems. Here, we find that the Arctic surface ozone during the 2020–2021 winter was evidently enhanced after the sudden stratospheric warming (SSW) onset based on reanalysis data and simulations of a state-of-the...
