title: Thematic datasets for the Tibetan Plateau from Tiangong-2 wide-band imaging spectrometer
title: 天宫二号宽波段成像仪青藏高原专题数据集

description: The Tibetan Plateau is known as the ridge of the world , the water tower of Asia, and the third pole of the earth. The Pan-Third Pole region, which extends from the third pole westwards to cover an area of about 20 million km2, constitutes the core area of the “Belt and Road”. The ongoing second comprehensive scientific investigation of the Tibetan Plateau intends to reveal the mechanism of environmental changes and optimize the ecological security barrier system in the Tibetan Plateau. It plays an important role in promoting the sustainable development of the Tibetan Plateau, the construction of national ecological civilization and the protection of global ecological environment. The launch of the Tiangong-2 wide-band imager in September 2016 has enabled a continuous observation of the Tibetan Plateau, which generated a large number of multi-temporal and multi-spectral remote sensing data. On this basis, we built the thematic datasets for the Tibetan Plateau based on a series of data processing and quality control measures, including radiation correction, geometric correction, and quantitative inversion. The datasets were then distributed and shared through the space application data promoting service platform for China Manned Space Engineering (http://www.msadc.cn). The datasets include high-quality image data, surface reflectance products and surface temperature products for the Tibetan Plateau acquired by the Tiangong-2 wide-band imaging spectrometer since its launch. It provides rich data for studies of land resources, lake hydrology, ecological environment and biodiversity, climate change, and glacial changes of this region.
