    Abstract
    An automatic soil observation network in typical ecosystems in China (SONTE-China) was established by the Aerospace Information Research Institute (AIR), Chinese Academy of Sciences (CAS), and National Engineering Research Center of Satellite Remote Sensing Applications(NECRSA), which were of the same unified sensor, unified sample design, unified acquisition depth, unified calibration method, unified data processing process. SONTE-China covers the main ecosystems (including grassland, farmland, desert and forest) and dry and wet climate zones in China. It can automatically obtain pixel scale soil temperature and soil moisture, which can not only serve the development and verification of high-resolution satellite remote sensing soil moisture products but also provide basic data for research in the fields of weather forecasting, flood forecasting, agricultural drought monitoring and water resources management.
