The world's first complex atmospheric observation system will be brought to Southwest China's Tibet autonomous region before October to monitor the atmosphere, experts said Sept 11.

The Atmospheric Profiling Synthetic Observation System (APSOS) is capable of monitoring the atmospheric composition, such as temperature, wind, ozone and carbon dioxide levels through remote sensing, the Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS) said on its website.

"The system was debugged in Anhui province's Huainan Atmospheric Physics (HAAS) and will soon be brought to the Yangbajain cosmic rays monitoring station in Tibet for extended atmospheric observation."

Located at 4,300 meters above sea level, the station is home to a great deal of research, including on cosmic rays.

APSOS is led by Lyu Daren, a professor at the CAS' Institute of Atmospheric Physics, who told the Global Times that "the system will be transported to Yangbajain station before October from Huainan city by trucks."

The system will be operational after at least one month of testing, Lyu said.

"The system is the world first complex atmospheric monitoring equipment, which can continuously monitor multiple atmospheric components in a specific location. It can monitor up to 110 kilometers," Lyu added.

Funded by the National Nature Science Foundation of China, the program was launched in 2012.

Lyu said data collected by APSOS will be a worldwide achievement.

"Its data, together with data collected on the ground and through satellites from other countries, can support world atmospheric research."

APSOS will improve China's overall level of atmospheric environment detection, offer valuable data on weather conditions and space security, CAS said.

APSOS is composed of five laser radars, a millimeter-wave cloud radar, a terahertz superconducting radiation spectrometer and telescopes, and can detect precise air quality through multiband detection technology, CAS explained.

"The Yangbajain cosmic rays monitoring station was chosen as the site for APSOS due to its high altitude. The terahertz superconducting radiation spectrometer can only work in altitudes above 3,000 kilometers," Lu Hong, a professor at CAS' Institute of High Energy Physics, told the Global Times on Sept 11.

The terahertz spectrometer is capable of penetrating the air and detecting remote targets through, CAS said.

It also said the system will receive simultaneous changes in the atmospheric components of an area, and can also capture transient atmospheric processes through high temporal resolution. The data will help researchers understand how the atmospheric layer affects solar and human activity, it said.

APSOS has been designed to operate at multiple wavelengths, ranging from ultraviolet to infrared and from terahertz to millimeter. It consists of several state-of-the-art instruments, for measuring range-resolved parameters of the whole (neutral) atmosphere, from surface up to 110 km, covering the altitude of troposphere, stratosphere, mesosphere, and the lower thermosphere.(Image by Cheng Xuewu)
