T1: Distribution of Glaciers in the TP and surroundings This data set contains 8 tables, the names and content are as follows:ĭata list: The data name list of the rest tables This paper report on the glacier status over the past 30 years by investigating the glacial retreat of 82 glaciers, area reductionof 7,090 glaciers and mass-balance change of 15 glaciers. Different glacier status with atmospheric circulations in tibetan plateau and surroundings. This data set is collected from the supplementary information part of the paper: Yao, T. Please refer to the following documents (in Chinese): "Design of Chinese Cryospheric Information System.doc", "Datasheet of Chinese Cryospheric Information System.DOC", "Database of the Tibetan Plateau.DOC" and "Database of the Tibetan Plateau 2.DOC".ĭoi: 10.11888/Geogra.tpdc.270050 25312 109 Requestable ģ.Different glacier status with atmospheric circulations in Tibetan Plateau and surroundings (1970s-2000s) Response model of plateau permafrost to global change (named "Fgmodel"): permafrost distribution data in 2009, 20 were projected. Socio-economic resources (Stations) : distribution of meteorological Stations on the Tibetan Plateau and it surrounding areas.Ĥ. Climate data: temperature, surface temperature, and precipitation.ģ. Hydrology: surface water (Stram_line), (Lake) Ĥ. Terrain: elevation, elevation zoning, slope, slope direction (DEM) The basic datasets of the Tibet Plateau mainly takes the Tibetan Plateau as the research region, ranging from longitude 70 - 105 ° east and latitude 20 - 40 ° north, containing the following types of data:Ģ. The establishment of Chinese Cryospheric Information System is to meet the needs of earth system science, to provide parameters and validation data for the development of response and feedback model of frozen soil, glacier and snow cover to global change under GIS framework on the other hand, it is to systemically sort out and rescue valuable cryospheric data, to provide a scientific, efficient and safe management and division for it Analysis tools.

Compared with some field GPS field measurement data and higher resolution remote sensing images (such as from QuickBird and WorldView), the glacial vector data in the second glacier inventory data set of China have higher positioning accuracy and can meet the requirements for glacial data in national land, water conservancy, transportation, environment and other fields. At the same time, the international general algorithm is used to calculate the glacier attributes, so that the vector data and attribute data that contain the glacier information of the main glacier regions in west China are obtained. The ice ridge extraction algorithm is developed to extract the glacier ice ridge, and it is used for the segmentation of a single glacier. Nyainqentanglha Mountains, Tibetan Plateau 1ġ.The second glacier inventory dataset of China (version 1.0) (2006-2011)Ĭhina's second glacier inventory uses the high-resolution Landsat TM/ETM+ remote sensing satellite data as the main glacier boundary data source and extracts the data source with the latest global digital elevation model, SRTM V4, as the glacier attribute, using the current international ratio threshold segmentation method to extract the glacier boundary in bare ice areas.
