Golmud, Qinghai, April 4 (Zhongxin Net) -- According to the relevant task requirements of China's second comprehensive scientific expedition to the Qinghai-Tibet Plateau (the second Qinghai-Tibet scientific expedition), from the proposal of planning to field site selection, from negotiation and determination to site construction, from equipment installation to test operation, the second Qinghai-Tibet scientific expedition project "Westwind-Monsoon Synergy and Its Impact" urgently needs to be newly built an important field observation station - Qaidam Basin Ground-atmosphere Interaction Golmud River Basin Wetland Comprehensive Observation Station (Golmud Wetland Station). It was finally built on the desert Gobi after more than a week and "many twists and turns".

This is the second Qinghai-Tibet scientific expedition "westerly-monsoon action area non-uniform underlying surface ground-gas interaction airborne flux observation" scientific expedition team, the Chinese Academy of Sciences Aerospace Information Innovation Institute (Chinese Academy of Aerospace Information Innovation) Earth observation water cycle and global change team established by the image of "grounded gas" wetland field observation station, and grassland station observation will have their own focus and complementary advantages, observe and collect regional ground-atmosphere interaction data in the Qaidam Basin, and help researchers carry out the ecological environment of the Qinghai-Tibet Plateau. Scientific research on the water cycle and global change.

In mid-April, before the next stage of the scientific expedition, researcher Jia Li, the leader of the Qinghai-Tibet scientific expedition team, the chief scientist of the Earth Observation Water Cycle and Global Change Team of the Aerospace Academy of the Chinese Academy of Sciences, and members of the scientific expedition took a group photo at the Golmud Wetland Station.
Jia Li pointed out that although the climate in the Golmud area is extremely dry, the Golmud River and its tributaries, which originate from the glaciers of the Kunlun Mountains and the snowmelt water, maintain the grasslands and wetlands of the Golmud River Basin, and the Golmud Wetland Station, which observes the interaction between the ground and atmosphere in the Qaidam Basin, is combined with the grassland station and the planned desert station to form a comprehensive dense observation network for the interaction between the earth and atmosphere under different ecological gradients and dry and wetland surface conditions in the Golmud area. It is an important ground-based observation component of the large-scale ground-based-space-based three-dimensional collaborative observation experiment mission to be launched this summer, providing ground verification information for space-based and space-based observations. At the same time, it will also change the lack of geo-atmosphere interaction observation data in the region, and is expected to provide "grounded" data support services for the ecological environment research of the Qinghai-Tibet Plateau and global climate change research.

Zheng Chaolei, a member of the Qinghai-Tibet scientific expedition team responsible for the data reception and processing of the two "grounded gas" observation stations in grassland wetlands and an associate researcher at the Aerospace Institute of the Chinese Academy of Sciences, said that the surface of the grassland station in operation is relatively dry, the vegetation cover is relatively sparse, and the newly built wetland station focuses on observing the meadows around the floodplain, there is seasonal water accumulation, the surface is relatively wet, and the vegetation is more luxuriant. After the completion of the Golmud Wetland Station, the research team can analyze the differences in the characteristics of ground gas exchange under different dry and wet land surface conditions in this area, and can more comprehensively understand the changes of ground gas exchange process characteristics in the Qinghai-Tibet Plateau.
"Before the soldiers and horses move, grain and grass go first", and the same is true of the new field sites of the Qinghai-Tibet scientific expedition. Jiang Min, assistant researcher at the Chinese Academy of Sciences' Aerospace Institute, said that it is very difficult to build a new field observation station in the desert Gobi, far from residential areas. After determining the construction site of the observation station, first purchase fences, wooden piles, wire, protective nets and other station construction materials, contact vehicles to transport the materials to the station construction site, and reasonably place various materials according to the site conditions, not only to meet the needs of the station, but also to ensure that the surface state is not damaged. The construction site is far from the urban area, and the scientific expedition team must bring dry food such as naan, cakes, and self-heating rice when they set out every day, and have an open-air picnic with wind and sand and cattle and sheep at the construction site. After the completion of the observatory, personnel need to be arranged to regularly maintain scientific research instruments and equipment, read observation data, and ensure the safety of instruments and equipment.

During the site selection process of the new station, Zhou Dingwang, a member of the Qinghai-Tibet scientific expedition team and a doctoral student of the Aerospace Institute of the Chinese Academy of Sciences, went deep into the pastoral area to visit herdsmen, do science popularization, and actively communicate with the local government to further understand the information of grassland owners. The vast desert Gobi is sparsely populated, and the members of the scientific expedition often drive hundreds of kilometers and cannot meet a herdsman, so he does not miss any opportunity to communicate with the herdsmen, breaking through from the point, connecting into a line, and gradually opening up the situation.
Bai Yu, a doctoral student graduating from the Chinese Academy of Sciences' Aerospace Academy this year, believes that in schools and laboratories, the algorithm results of soil moisture are just a variable (or number), but when they come to the field observation site, soil moisture becomes the humidity that the palm of the researchers' hands can touch. Participating in the Qinghai-Tibet scientific expedition "made me understand more that scientific knowledge is like a tree, textbooks or documents are like the branches of a big tree, and going deep into nature and experiencing its wonderful changes will make the tree of science grow full of green leaves and flowers."

Lv Yunzhe, a member of the Qinghai-Tibet scientific expedition and a doctoral student at the Aerospace Institute of the Chinese Academy of Sciences, said that if the laboratory of life science students is a variety of test tubes and beakers, then the laboratory of earth science students is a vast land, the measuring instrument is the detection reagent, and the physical process between various features is the experiment to capture the target. No matter how high-precision remote sensing images are in the computer, they cannot depict the natural scenery and real sights encountered on the road of scientific expeditions. Walking out of the laboratory, scientific research work is no longer the "0" and "1" in the computer for him, but has become mountains and rivers, sunshine, rain, wind and dust, and can also understand earth science more specifically.
The Qinghai-Tibet scientific expedition member and doctoral student of the Aerospace Institute of the Chinese Academy of Sciences had the first impression of Golmud, which was full of barrenness, whitened saline-alkali land, and extreme dryness, until he went deep into the grassland to select and build a site for the Golmud Wetland Station, only to find that such an arid place had given birth to a dense river network and turbulent water. He said that his research work is related to glaciers, and after the field trip, he not only felt that glaciers and glacial meltwater have important significance and impact on surrounding areas, especially arid areas, but also stimulated the interest and motivation for the study of glacier changes on the Qinghai-Tibet Plateau.

Jia Li concluded that although the field environment is harsh and arduous, the process is difficult and complicated, but the Qinghai-Tibet scientific expedition is a sacred and glorious task, and the new Golmud Wetland Station, as one of the most important tasks of this Qinghai-Tibet scientific expedition, has been supported by the Qinghai-Tibet Plateau cryosphere observation and research station of the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences in Golmud. The Golmud Wetland Station was finally completed and put into operation, laying a solid foundation for the follow-up large-scale space-air-ground joint experiment mission of the Qinghai-Tibet scientific expedition, and also providing a rare learning and practice opportunity for young doctoral expedition members to personally understand the spirit of scientists and practice "writing papers on the motherland".
In the next step, based on the accumulation of scientific expeditions in Qinghai-Tibet and the data of comprehensive observation sites in the field such as Golmud Wetland Station and grassland station, the team of the Aerospace Institute of the Chinese Academy of Sciences will comprehensively and deeply carry out research on the geo-atmosphere interaction mechanism of the Qinghai-Tibet Plateau, so as to provide more and better "grounded gas" observation data and research results for the ecological protection of the Qinghai-Tibet Plateau and the high-quality development of the national economy, and contribute Chinese wisdom to global climate change research.
