On the afternoon of September 25th, a research group of the Institute of Atmospheric Physics of Chinese Academy of Sciences was doing experiments at the sounding station of Zhangqiu Meteorological Bureau in Jinan, Shandong Province. Because the rope was broken, a probe balloon and its scientific research instrument drifted away with the wind. According to radar, high-altitude wind direction, wind speed and other information, the research group preliminarily judged that the balloon finally landed in Zichuan area of Zhoucun, Zibo.

Balloons with instruments floated away with the wind, and researchers said that after offering rewards, they would receive fraudulent calls.

The researchers offered a reward of 4,000 yuan for clues to find the lost balloons and scientific instruments, and published their contact numbers.

On the morning of September 27th, around 10, researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences told this newspaper that up to now, balloons and related scientific instruments have not been found, and many fraudulent calls have been received. However, the staff member did not disclose more information.

Did you call the police about the missing balloon? A meteorologist in Zhangqiu City who helped to find relevant instruments said that the researchers of the research group have not reported this matter yet.

A project leader in lasg told the newspaper that the incident was only noticed by the media because the students made friends by chance. He also said that at present, they have received clues provided by multiple telephones and are currently confirming them.

According to the meteorological staff of Zhangqiu mentioned above, at present, they have received clues and students have described that a similar balloon recently fell and was picked up near Shandong Vocational College of Light Industry in Zibo. At present, researchers still don't know who owns balloons and instruments.

According to the information from official website, Institute of Atmospheric Physics, Chinese Academy of Sciences, the research fields of relevant researchers are comprehensive detection of atmospheric components and environmental climate effects of atmospheric aerosols.

Researchers hope to find balloons and retrieve data from relevant scientific instruments for subsequent research. Conventional probe balloons used in high-altitude weather stations will burst automatically after rising to a height of about 30 kilometers. Sounding balloons are mainly used to carry radiosondes to high altitude to detect meteorological elements such as temperature, pressure, humidity and wind.
