Major events
The entire system includes a ground receiving system and airborne suspension instruments
Air suspension instruments include atmospheric detection probes containing temperature, humidity, pressure, wind and meteorological elements (ozone probe and aerosol spectrum probe are optional)
Aerial suspension instruments can be hung under airships or balloons.
The atmospheric element probe can be used separately, integrated with the ozone probe ECC, or integrated with the aerosol spectrum probe LOAC.
During the operation of the entire system, airborne instruments automatically and continuously observe atmospheric composition and multiple elements. The observed data can be automatically sent to the ground control receiving and processing system for data processing, providing scientific research and business needs

4. Temperature and humidity sensors.
5. Pressure calculation.
6. External switch.
7. Powered by dry batteries, with a lifespan of many years.
8. The transmission adopts a digital synthesizer that complies with the European ETSI EN 302054 standard.
9. Supports data transmission per second,
10. The interface is compatible with ozone probes.
Aerosol probe:
Mainly used to detect the number concentration of 20 types of aerosol particles within the range of 0.3-100 μ m diameter (10 types within the range of 0.3-5 μ m diameter) (unit: particles/cm)3）.
This device can be used for long-term monitoring of aerosol particle number concentration in polluted areas, sandstorm areas, and volcanic ash areas in the middle and lower atmosphere, and to elucidate the physical properties of particles.
By applying new optical designs, LOAC can evaluate the main physical properties of particles within five diameter ranges (<1 μ m, 1-5 μ m, 5-10 μ m, 10-20 μ m,>20 μ m). These particles are mainly liquid aerosol particles, carbon particles (such as coal smoke particles), and non carbon aerosol particles (mainly mineral particles).
(Above) Integrating LOAC and M10-GPS sounding instruments under the sounding balloon to obtain real-time atmospheric data. This device has an integrated device with a total weight of less than 1kg
Ozone detector:
