Taklamakan Desert Meteorological Field Scientific Experiment Base Observation Data

The Taklamakan Desert Atmospheric Environment Observation and Experiment Station was established in 2003 by the Urumqi Institute of Desert Meteorology of the China Meteorological Administration (CMA), and in 2018 it was selected as one of the first field scientific experiment bases of the CMA, named as the Taklamakan Desert Meteorological Field Scientific Experiment Base. The base is located in the Ta Zhong area in the hinterland of the Taklamakan Desert in Xinjiang, China, and is the only atmospheric environment observation and test base in the world that goes deeper than 200 km into the hinterland of the flowing desert. It is the ideal natural test site for the study of atmospheric boundary layer physical processes, desert atmospheric environment and desert land surface processes in flowing deserts. It is an ideal natural test site for the study of the physical processes of the mobile desert atmospheric boundary layer, desert atmospheric environment and desert land surface processes. The main observation system of the test site includes five types of stations, including a super station, a desert flux station, a regional weather station, a sandstorm monitoring station and an atmospheric composition monitoring station. The super station consists of an 80m high 10-layer gradient tower detection system, radiation detection system, vortex correlation detection system, tethered airship detection system, and wind profile radar detection system, which is used to observe the near stratigraphic structure of the Taklamakan Desert, water and heat flux exchange, surface radiation energy budget, boundary layer meteorological elements and vertical distribution of sand and dust concentration.

Oasis and Desertification Processes in Arid Zones and their Response to Human Activities, Climate Change and Regulation of 973 Program

The project "Oasis and Desertification Processes in Arid Zones and Their Response and Control to Human Activities and Climate Change" was established in 2009 under the National Key Basic Research and Development Program of China (973). The project optimized the ecodynamic model of vegetation, established a unit hydrological model, and simulated and analyzed the threshold values of hydrological variables for oasis and desertification in watersheds. The data sets include: the contribution of human activities and climate change to the process of oasis and desertification in a typical area; the analysis of the contribution of human activities and climate change to the process of oasis and desertification in a typical area; and the completion of the regulation zone of the process of oasis and desertification. The open data sets include data on oasis, desertification, salinization and land use in the Northwest Arid Zone (NWARZ) of different ages; data on water, soil, air and biotic processes and changes in typical areas of oasis and desertification; data on key physical processes of oasis and desertification and their numerical simulations; data on hydrological processes in typical watersheds; and data on typical watersheds. Historical reconstruction data; socioeconomic and environmental benefit assessment data. The data sets mainly span from 1950 to 2013, including spatial and temporal distribution changes, long-term observations, field surveys, remote sensing inversion, model simulations, and experimental analyses. Among them, there are 74 spatial and temporal distribution data; observation data including nearly 2 million data from 14 observation stations; 17 remote sensing inversion and reconstruction data sets; 3 survey reports; 15 representative papers and supporting data.

Thematic data for High quality development of the Yellow River Basin

The Yellow River is the second largest river in China. It originates from the Yueguzonglie basin which is at the northern foot of Bayan Kala mountain, is 4500m above sea level on the Qinghai Tibet Plateau. The yellow river runs through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shanxi, Shaanxi, Henan, Shandong and other nine provinces and regions, it runs into Bohai Sea in Kenli area of Shandong Province. The river has full-length 5464km of main stream, 4480m drop heights and 795000 km2 of drainage area (including 42000 km2 of internal flow area). This thematic data set includes the integrated geography factors, land cover, DEM elevation, administrative division, satellite remote sensing, climate, natural hazards and other data of the Yellow River Basin.

Investigation of ice volume changes in the center of glacier action in western China

Based on the research on the response of glaciers to climate change and the impact on water resources and disasters in Western China, the main glacial central action areas in Western China are selected: Youyi peak area of Altai mountain, Daxue mountain and lenglong mountain area of Qilian Mountain, Bogda and Tomur peak area of Tianshan Mountain, MUZTAG mountain, qiaogoli peak area, main mountain peak key glacier area of Kunlun Mountain and Gongga mountain In the main peak area, remote sensing is used as the main data acquisition method, combined with the field ice surface elevation survey, to carry out the ice quantity change investigation. Mass balance observation and repeated GPS measurements were carried out on Typical Glaciers (No.1 glacier of Urumqi River, No.12 glacier of Laohugou Valley, No.71 glacier of Qilian Mountain, coal mine glacier in Kunlun Mountain and No.1 glacier in Baishuihe River) to monitor the change process of ice amount, and to form the special data of glacier ice amount change of major glaciation centers in Western China. Among them, the data of Glacier Mass Balance and subglacial topography are still in the one-year protection period, and other data have been open to access.
