Investigating long-term changes in polar stratospheric clouds above antarctica during past decades: a temperature-based approach using spaceborne lidar detections

HIGHLIGHTS

• What: The authors focus only on the South Pole (May- October). MAE minima are well-defined enough to specify a Tpsc with a precision of 1-2 K. Below the authors compare the retrieved Tpsc with the temperature of nitric acid nucleation TNAT, which is the warmest temperature at which PSC particles can in theory start to form and subsist, considering all available chemical species (Tritscher at al., 2021). For the 50-70 hPa pressure level of the estimated PSC densities Fd0 (P ) derived from the model (Sect 3.1) are shown in Appendix C. Atmos. The . . .
