WebMar 9, 2024 · Abstract. Polar stratospheric clouds (PSCs) play an important role in the spatial and temporal evolution of trace gases inside the polar vortex due to different processes, such as chlorine activation and NOy redistribution. As there are still uncertainties in the representation of PSCs in model simulations, detailed observations of PSCs and … Webthick (optical depth unity) polar stratospheric clouds (PSCs) in a GCM, in combination with increased greenhouse gas con-centration, producing a temperature distribution more …

Polar Stratospheric Clouds: Satellite Observations
WebIce particles found within polar stratospheric clouds (PSCs) and upper tropospheric cirrus clouds can dramatically impact the chemistry and climate of the Earth's atmosphere. The … WebApr 4, 2024 · Polar stratospheric clouds (PSCs) play important roles in stratospheric ozone depletion during winter and spring at high latitudes (e.g., the Antarctic ozone hole). PSC particles provide sites for heterogeneous reactions that convert stable chlorine reservoir species to radicals that destroy ozone catalytically. WebThe role of polar stratospheric clouds in polar ozone loss has been well documented. The CALIPSO satellite mission offers a new opportunity to characterize PSCs ... established that polar stratospheric clouds (PSCs) play an essential part in the springtime chemical depletion of ozone at high latitudes (Solomon, 1999). The role of PSCs is twofold. monitor stand laptop underneath
