14 years of lidar measurements of polar stratospheric clouds at the French Antarctic station Dumont d’Urville
International audience Polar Stratospheric Clouds (PSC) play a critical role in the stratospheric ozone depletion processes. The last 30 years have seen significant improvements in our understanding of the PSC processes but PSC parametrization in global models still remains a challenge, due to the n...

International audience Polar Stratospheric Clouds (PSC) play a critical role in the stratospheric ozone depletion processes. The last 30 years have seen significant improvements in our understanding of the PSC processes but PSC parametrization in global models still remains a challenge, due to the necessary trade-off between the complexity of PSC microphysics and tight model parametrization. The French Antarctic station Dumont d'Urville (DDU, 66.6 • S-140.0 • E) has one of the few high latitude ground-based lidars in the Southern Hemisphere that has been monitoring PSC for decades.
