China News Service, Beijing, December 1 (Reporter Sun Zifa) The Institute of Qinghai-Tibet Plateau of the Chinese Academy of Sciences released news on December 1 that the Institute of Geo-Atmosphere and Climate Effects team Ma Yaoming After more than 20 years of hard work, researchers and others have recently researched and integrated the first set of high-time-resolution long-term comprehensive observational data sets for the Qinghai-Tibet Plateau land-atmosphere interaction, which has recently been released to the world, and related research results have also been published in the international journal Earth System Science Data .
This data set can be widely used in Earth system science research, such as the analysis of meteorological element characteristics of the Qinghai-Tibet Plateau, the evaluation of remote sensing products, the development of remote sensing inversion algorithms, and the evaluation and development of numerical models. It will integrate Earth system science , The impact and response of key areas to global changes, and the construction of ecological security barriers in the Qinghai-Tibet Plateau and its adjacent areas provide a solid and reliable scientific basis.
According to the Institute of Qinghai-Tibet Plateau, Chinese Academy of Sciences, the ground-atmosphere and climate effects team conducted long-term and continuous research on the Qinghai-Tibet Plateau and established large-scale terrain covering the plateau mountains, alpine meadows, alpine grasslands, desert Gobi, A comprehensive observation and research platform for the Qinghai-Tibet Plateau land-atmosphere interaction on the typical underlying surfaces of plateaus such as desert grasslands, alpine forests, and plateau lakes. The atmospheric boundary layer, soil water and heat changes, and land- Long-term observation and research on the law of energy and water exchange between air. On this basis, the first set of long-term comprehensive observation data sets of land-atmosphere interaction on the Qinghai-Tibet Plateau with high time resolution was released.
Researcher Ma Yaoming pointed out that observational research is an important means for the development of earth system science. The Qinghai-Tibet Plateau is a typical area that reflects the interaction of different spheres of the climate system and their effects. However, due to the constraints of the natural environment, complex topography and underlying surface characteristics, the Qinghai-Tibet Plateau comprehensive observation station network is sparse and the meteorological stations are poorly representative. There are large uncertainties in the satellite inversion products in the plateau area. Therefore, it is the most lack of observational data in China. One of the regions in China has severely hindered scientists’ scientific understanding of the land-atmosphere interaction process and the laws of water cycle on the Qinghai-Tibet Plateau, restricting the development of numerical models and the improvement of China’s severe weather and climate prediction.
In order to make up for the serious lack of comprehensive observational data on the Qinghai-Tibet Plateau, and to deeply understand the interaction process and mechanism of the various surface layers in the region under the conditions of climate change, the Institute of Qinghai-Tibet Plateau of the Chinese Academy of Sciences and the Northwestern Chinese Academy of Sciences Research on Ecological Environment Resources The Chinese Academy of Sciences and other scientific research institutes have conducted long-term observation and research on the atmospheric boundary layer of different underlying surfaces of the Qinghai-Tibet Plateau, changes in soil water and heat, and the law of energy and water exchange between the earth and the atmosphere.
Ma Yaoming said that the data set released this time comprehensively sorts out the atmosphere and environment of Everest, the alpine environment of southeast Tibet, the Namco multi-circle, the desert environment of Ali, the environment of the Muztag west wind belt, and the alpine climate of Nagqu. Several comprehensive observation and research stations of the Chinese Academy of Sciences, hour by hour meteorological gradient, four-component radiation, soil and atmospheric turbulence</span from 2005 to 2016 > The other observation data are the comprehensive observation data of field stations with the highest time resolution, the longest observation sequence, and the most complete observation elements on the Qinghai-Tibet Plateau.
It is understood that the first long-term comprehensive observation data set of land-atmosphere interaction on the Qinghai-Tibet Plateau with high time resolution has been publicly released in the National Qinghai-Tibet Plateau Science Data Center and the Chinese Academy of Sciences Science Data Repository for global scientific research users Query and download to use.
