The airborne atmospheric component detection subsystem developed by Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science, which is an important part of the airborne remote sensing system has participated in the first flight test of the Xinzhou 60 aircraft organized by the Aerospace Information Research Institute, Chinese Academy of Sciences.

Two flights were carried out in the subsequent tests, which is provided an important basis evidences for confirming the acceptance of the subsystem through the overall system.

The airborne atmospheric component detection subsystem consists of four components: atmospheric detection laser radar, differential optical absorption spectrometer, Multi-angle polarized radiometer and master control manager. Using the combination of active and passive light detection technology, the sub-system can use the combination of active and passive light detection technology to obtain real-time information on of the vertical distribution of atmospheric aerosol optics and microphysical properties on the flight path, and the concentration distribution of atmospheric pollutant gases (SO2, NO2, etc.), which can provide data support for locating and investigating pollution sources location and troubleshooting.

The results can be used as an effective supplement to for ground-based or space borne monitoring instruments and spaceborne instrument measurement, which is a powerful means to for quick obtain accessing regional pollution information and research studying pollution processes.

In this test, under the dispatch of the master control manager, the airborne atmospheric component detection subsystem firstly performed a series of functional tests on the atmospheric detection laser radar, differential optical absorption spectrometer and multi-angle polarized radiometer, such as self-test self-inspection, preheating, measurement, shutdown and so on.

Atmospheric environmental telemetry data such as trace gases (NO2, SO2), aerosols (such as extinction coefficient, optical thickness, and refractive index) were obtained during the flight path.

Its relevant data and processing results could be used to study trace gases, atmospheric aerosol optics and temporal and spatial distribution of microphysical properties.

The success of the first flight of the Xinzhou 60, marks China’s airborne remote sensing system for major science and technology infrastructure construction projects successfully entering into the system flight test and test phase for the airborne remote sensing system.
