Association of Antarctic polar stratospheric cloud formation on tropospheric cloud systems, Geophys
[1] The formation of polar stratospheric clouds (PSCs) is critical to the development of polar ozone loss. However, the mechanisms of PSC formation remain poorly understood, which affects ozone loss models. Here, based on observations by the NASA A-train satellites, we show that 66% ± 16% and 52% ±...
