Atmospheric profiling synthetic observation system (APSOS).

An NSFC (National natural Science Foundation of China) funded research facility aims to deepen our understanding about the interactions within neutral atmosphere layers, i.e., Planetary Boundary layer (PBL), Upper Troposphere-Lower Stratosphere (UT-LS), stratosphere, Mesopause and Lower Thermosphere (MLT), as well as the response of atmospheric processes to solar activities from the top, and the natural and anthropogenic influences from the Earth surface.
