"Peak Mission" Mount Everest Scientific Expedition Atmospheric Ozone Vertical Sounding Experiment Completed

　　On May 6, the Everest Atmospheric and Human Health Scientific Expedition Team completed the vertical sounding experiment of atmospheric ozone in the Mount Everest area. A total of ten air sounding balloons were released in the experiment, and the highest balloon flew to the sky 39.1 kilometers away from the Mount Everest base camp .

　　At 12:00 noon on May 6, the tenth exploratory balloon release experiment was launched at the Everest Base Camp.

The helium-filled balloon, after an hour and a half of flight, stayed in the air 38.2 kilometers from the base of Mount Everest.

This is not the highest soaring balloon in the experiment.

According to experts, the air balloon has previously flown as high as 39.1 kilometers from the base of Mount Everest.

　　Zhu Tong, Academician of the Chinese Academy of Sciences, Dean of the School of Environmental Science and Engineering of Peking University: We want to see ozone, ozone in the stratosphere, it shields the sun's ultraviolet rays, so we have a protective layer of ozone, so it is good ozone.

But after reaching the ground, ozone is very active.

It can enter our respiratory system and cause harm to human health.

Now we can know a distribution of ozone from ground to high altitude through ozone sounding.

Then we can know how much is generated on the ground, and how much is teleported from the stratosphere to the ground above.

It has a very important effect on our health and on our atmosphere.

　　So, the altitude of the ten air exploration balloons is between 30 and 40 kilometers above the base of Mount Everest. What does this altitude mean?

　　Zhu Tong, Academician of the Chinese Academy of Sciences, Dean of the School of Environmental Science and Engineering, Peking University: We are concerned about the concentration of ozone in this layer, its various (influenced) causes, and how it may be transported through the exchange of air convection. When you come to the ground, you will have a more comprehensive and systematic understanding.

So to 39 kilometers is basically a concentration that perfectly covers the entire ozone layer.

There is some ozone in the middle of the stratosphere, and its concentration covers a height of about 30 to 40 (km).

So we can cover it and get a more perfect data.

This data is very important for us to understand the evolution of the atmosphere in the entire Qinghai-Tibet Plateau, especially in the Mount Everest region.
