Recent Progress of APSOS-Tibet System Observation-Current Status and Future Plan

To understand the dynamics-physics-chemistry processes of the whole atmosphere, from earth surface to lower thermosphere, a synthetic observation system was established over the Tibetan Plateau at the end of 2017. This system consists of 5 lidars, 2-micrometer wave cloud radars, a THz spectrometer, and a set of surface meteorological observation instruments as well as atmospheric environmental instruments. The system, we call it as APSOS, is located in central Tibet, Yangbajing, at the altitude of 4300m ASL. During the last 2 years, quasi-continuous observations are made for different realms. A set of observation data have been collected for future analysis. Some of the system ability and case study has been achieved and further work plan will be presented in this paper.
