Meteorological data of the integrated observation and research station of Ngari for desert environment (2009-2017)

The data set includes meteorological data from the Ngari Desert Observation and Research Station from 2009 to 2017. It includes the following basic meteorological parameters: temperature (1.5 m from the ground, once every half hour, unit: Celsius), relative humidity (1.5 m from the ground, once every half hour, unit: %), wind speed (1.5 m from the ground, once every half hour, unit: m/s), wind direction (1.5 m from the ground, once every half hour, unit: degrees), atmospheric pressure (1.5 m from the ground, once every half hour, unit: hPa), precipitation (once every 24 hours, unit: mm), water vapour pressure (unit: kPa), evaporation (unit: mm), downward shortwave radiation (unit: W/m2), upward shortwave radiation (unit: W/m2), downward longwave radiation (unit: W/m2), upward longwave radiation (unit: W/m2), net radiation (unit: W/m2), surface albedo (unit: %). The temporal resolution of the data is one day. The data were directly downloaded from the Ngari automatic weather station. The precipitation data represent daily precipitation measured by the automatic rain and snow gauge and corrected based on manual observations. The other observation data are the daily mean value of the measurements taken every half hour. Instrument models of different observations: temperature and humidity: HMP45C air temperature and humidity probe; precipitation: T200-B rain and snow gauge sensor; wind speed and direction: Vaisala 05013 wind speed and direction sensor; net radiation: Kipp Zonen NR01 net radiation sensor; atmospheric pressure: Vaisala PTB210 atmospheric pressure sensor; collector model: CR 1000; acquisition interval: 30 minutes. The data table is processed and quality controlled by a particular person based on observation records. Observations and data acquisition are carried out in strict accordance with the instrument operating specifications, and some data with obvious errors are removed when processing the data table.

Time-lapse observation dataset of soil temperature and humidity on the Tibetan Plateau (2008-2016)

This data set comprises the plateau soil moisture and soil temperature observational data based on the Tibetan Plateau, and it is used to quantify the uncertainty of model products of coarse-resolution satellites, soil moisture and soil temperature. The observation data of soil temperature and moisture on the Tibetan Plateau (Tibet-Obs) are from in situ reference networks at four regional scales, which are the Nagqu network of cold and semiarid climate, the Maqu network of cold and humid climate, and the Ali network of cold and arid climate,and Pali network. These networks provided representative coverage of different climates and surface hydrometeorological conditions on the Tibetan Plateau. - Temporal resolution: 1hour - Spatial resolution: point measurement - Measurement accuracy: soil moisture, 0.00001; soil temperature, 0.1 °C; data set size: soil moisture and temperature measurements at nominal depths of 5, 10, 20, 40 - Unit: soil moisture, cm ^ 3 cm ^ -3; soil temperature, °C

Dataset of typical glacier changes on Tibetan Plateau and Its surrounding areas (2005-2016)

This is the data set of typical glacier changes on the Tibetan Plateau and its surrounding areas, which includes the Qiangyong Glacier near Yamdrog Yumtso, the Palong Glacier in the Palongzangbu River Basin, the Xiaodongkemadi Glacier on Tanggula Mountain in the central Tibetan Plateau, the No. 2 Anglong Glacier in the Ngari Prefecture in the western Tibetan Plateau, the Aerqieteke Glacier in the Muztagata region, the No. 15 Glacier, the Qiaodumake Glacier, and the Qiyi Glacier in the Qilian Mountains on the northeastern Tibetan Plateau. It can be used to study the response of typical glaciers in typical areas of the plateau to climate change. On the ice surface of a typical glacier in a typical area, a steam drill is used to set a length rod. The height of the rod is measured at a fixed time every year and combined with snow pit observations to observe the glacier mass balance. Marks are set on the ground near the terminus of the glacier, and the distance between the marker and the terminus of the glacier is measured to observe changes in the position of the terminus of the glacier. Among the glaciers, there are terminus change data for the Qiaodumake Glacier and No. 94 Palong Glacier. In the data set processing method, a continuous sequence of time and space is formed after the quality control of the original data. It conforms to the accuracy of conventional glacier monitoring and research in China and the world, and it meets the requirements of the comparative study of glacier changes and related climate change records.
