The SMN-SDR network is located in China and it consists of 34 stations measuring soil moisture and soil temperature. Of the 34 stations, there are 20 stations collecting precipitation measurements as well. The soil moisture sensors are positioned at five measuring depths (3, 5, 10, 20, and 50 cm). The data is available from June 2018 until the end of 2019. For information on how to calibrate the raw soil moisture data before usage, see here.

We would like to thank Tianjie Zhao for providing us with the data and for the support during the implementation process.
