Access notes
An account is required. Higher access levels may require additional verification such as a Chinese phone number or Chinese identification. The English interface provides less data than the Chinese interface.
Video tutorial
How to register, search and identify downloadable datasets.
The repository provides illustrated guidance explaining how to register, search for data, and submit applications for downloading datasets.
Access notes
Users must create an account before accessing data. Researchers outside China can generally obtain only the lowest access level, which allows downloads of up to five online data entries and five offline data entries per day.
Downloading also requires users to state the purpose of data use and submit an application. According to the source information, this review step currently appears to function mainly as a formality rather than a substantive evaluation. The Chinese interface is recommended because the English version contains substantially less data.
Repository overview
The center was established to integrate Earth system science data from domestic and international sources and to support scientific research as well as sustainable socio-economic development. It collects data from research institutions, universities, and major national scientific projects.
Its holdings focus especially on land surface systems and human–land interactions, making it a key resource for geoscientific and geographical research in China.
