Airborne Atmospheric Sounding System

The airborne atmospheric detection system is equipped with advanced cloud particle macroscopic and microscopic detection equipment to collect cloud macroscopic and microscopic data information in real time, which is used to detect and analyze cloud microphysics and macroscopic weather conditions in the high-altitude environment, so as to further grasp the regional air clouds. The dynamics of water resources and operating conditions in the cloud provide data support for weather detection and operations.

Program Elements

The airborne atmospheric detection system is mainly composed of the airborne atmospheric environment macro parameter measurement system and the airborne microscopic particle measurement system. The airborne atmospheric environment macro parameter measurement system includes a cloud total moisture measurement subsystem, an atmospheric data measurement subsystem, a flight attitude measurement subsystem, a data receiving and display subsystem and an airborne dew point meter. The airborne microscopic particle measurement system consists of PCASP-100X passive cavity aerosol probe, CCP cloud particle combination probe, PIP precipitation imager, CCN cloud condensation nucleus counter, PADS particle analysis display system, external probe cable and customized cabinet.

Program Features
