Climatology of Arctic polar stratospheric clouds as measured by lidar in Ny-Alesund, Spitsbergen [79° N,12° E]
Polar stratospheric cloud (PSC) measurements have been taken by means of a lidar system at the German Koldewey Station in Ny-Ålesund, Spitsbergen [79°N, 12 °E], since 1988. Here we present the first PSC climatology for the high Arctic built on Ny-Ålesund lidar data collected from winter 1995/1996 to...
