STORYLINE:

The China Global Atmosphere Watch Baseline Observatory stands on China's Qinghai-Xizang plateau, where it has been in operation for 30 years. 

It is one of 32 global baseline observatories established by the World Meteorological Organization. Standing more than 3,800 meters above sea level on Waliguan mountain, it's the world's highest of its kind.

Deputy director Wang Jianqiong has been working at the observatory since 2003.

"Over the past 30 years, generations of meteorologists have accumulated a large amount of atmospheric composition observation data through their own persistence and dedication. The data have made great contributions to the global response to climate change."

The average annual temperature at the station is below 0 degrees Celsius, and the average annual oxygen content is equivalent to 67 percent of that at sea level. 
   
In order to ensure that the observation quality at Waliguan is not negatively affected, no industrial or mining enterprises are developed within a radius of 50 kilometers. The nearest town is more than 20 kilometers away.
   
Currently, the observatory is capable of producing over 60,000 data pieces each day and monitoring major atmospheric components.

One of the most significant achievements of the past 30 years is the "carbon dioxide curve," also known as the "Waliguan curve." Updated annually, it is drawn from observations at the station.
   
Data produced via the Waliguan curve are consistent with observation data gathered by Mauna Loa Observatory in Hawaii since the 1950s. The observations have become an important basis for proving global climate change and supporting the United Nations Framework Convention on Climate Change.
