Photos of domestic animals in Qinghai Tibet Plateau (2018-2019)

In order to describe the distribution pattern of genetic diversity of the main domesticated animals in the Qinghai Tibet Plateau and its surrounding areas, clarify their genetic background, and establish the corresponding genetic resource database, the undergraduate team collected local animals in Dali, Yunnan, Shangri La, Mangkang, Luqu, Chayu, Changdu, Hetian and Yili regions from 2018 to 2019 The blood or tissue samples of the animals were collected, and the corresponding individual photos were taken at the same time. Each folder contains a set of photos of local domestic animals and a sample information sheet. Photos are stored in JPG format. The information table records the basic sample information such as species, species, detailed sampling place, sample type, collection time, collector and storage method, and stores them in the form of Excel.

Basic meteorological data of glacier moraine area at 24K in Galongla, Southeast Tibet station, Chinese Academy of Sciences (2018-2019)

The data are collected from the automatic weather station (AWS, Campbell company) in the moraine area of the 24K glacier in the Southeast Tibet Plateau, Chinese Academy of Sciences. The geographic coordinates are 29.765 ° n, 95.712 ° E and 3950 m above sea level. The data include daily arithmetic mean data of air temperature (℃), relative humidity (%), wind speed (M / s), net radiation (w / m2), water vapor pressure (kPa) and air pressure (mbar). In the original data, an average value was recorded every 30 minutes before October 2018, and then an average value was recorded every 10 minutes. The temperature and humidity are measured by hmp155a temperature and humidity probe. The net radiation probe is nr01, the atmospheric pressure sensor probe is ptb210, and the wind speed sensor is 05103. These probes are 2 m above the ground. Data quality: the data has undergone strict quality control. The original abnormal data of 10 minutes and 30 minutes are removed first, and then the arithmetic mean of each hour is calculated. Finally, the daily value is calculated. If the number of hourly data is less than 24, the data is removed, and the corresponding date data in the data table is empty. In addition to the lack of some parameter data due to the thick snow and low temperature in winter and spring, the data can be used by scientific researchers who study climate, glacier and hydrology through strict quality control.

Basic meteorological data of Yigong (2018-2019)

This data is the data of the automatic weather station (AWS, Campbell company) set up in Yigong Zangbu basin by the Southeast Tibet alpine environment comprehensive observation and research station of Chinese Academy of Sciences in 2018. The geographic coordinates are 30.1741 n, 94.9334 e, and the altitude is 2282m. The underlying surface is grassland. The data include daily arithmetic mean data of air temperature (℃), relative humidity (%), wind speed (M / s), water vapor pressure (kPa) and air pressure (MB) and daily accumulated value of precipitation. The original data is an average value recorded in 10 minutes. The temperature and humidity are measured by hmp155a temperature and humidity probe. The rainfall instrument is tb4, the atmospheric pressure sensor is ptb210, and the wind speed sensor is 05103. These probes are 2 m above the ground. Data quality: the quality of the original data is better, less missing. The data station is a meteorological station in the lower altitude of the Qinghai Tibet Plateau, which will be updated from time to time in the future. It can be used by researchers studying climate, hydrology, glaciers, etc.

The elevation data set of hambantota port area with 5-meter resolution (2018-2019)

The elevation data set of Hambantota port area with 5-meter resolution is obtained from the stereo image pair data of ZY-3 satellite. ZY-3 carried four optical cameras, including an emmetropic panchromatic TDI CCD camera with a ground resolution of 2.1m, a forward and backward panchromatic TDI CCD camera with a ground resolution of 3.5m, and an emmetropic multispectral camera with a ground resolution of 5.8m. Among them, the three line array stereo image pairs formed by push broom imaging of forward looking and back looking panchromatic cameras can be used for DEM extraction. Through the retrieval of the transit information and data of ZY-3 from 2018 to 2019, the cloudless stereo images of hambantota area are selected for DEM extraction. The steps including defining ground control points, connection points, setting DEM extraction parameters and editing results.

Meter resolution image data set of Hanbantota port area (2018-2019)

The meter resolution remote sensing image data of hanbantota area is composed of data fusion and splicing of different satellites. Multispectral remote sensing images with resolution between 0.5 m and 1 m from 2018 to 2019 are selected, and cloud free data with similar time are selected, and the result data set is formed by cutting and splicing according to the research area. The spatial resolution of the data is about 0.6 meters. The data is mainly used to study the high-precision extraction of disaster bearing body elements, such as port facilities, roads and so on. The extracted thematic elements will be used as the basic data of storm surge exposure and vulnerability analysis.

Genomic variation data of modern Tibetans

The average altitude of the Tibetan Plateau is more than 4000 meters. The harsh environment such as high cold and low oxygen poses a huge challenge to human survival. However, since the late Paleolithic period, Tibetan people in the plateau have reached the Plateau, and in the Neolithic period, people began to permanently settled on the high-altitude areas on a large scale. The history of population migration in this process has become the focus of different fields. In order to analyze the genetic structure of Tibetan population from the perspective of the whole genome and trace back the history of human settlement on the plateau, we obtained the whole genome variation data of 20 Tibetan individuals. The SNP typing of 20 samples was carried out by DNA array method, and about 700000 loci (including nuclear genome, mitochondrial DNA and Y chromosome) of each sample were obtained. Based on the above data, relevant biological information analysis (mainly including chip site quality control analysis, Y chromosome and mitochondrial DNA haplotype analysis) was carried out. This data is helpful to analyze the genetic structure of Tibetan population from the perspective of nuclear genome, Y chromosome and mitochondrial DNA. By comparing with the data of people around the plateau, we can trace the migration and settlement history of the plateau population comprehensively.
