A dataset of hourly profile soil temperature at Hailun Ecological Station in Northeast black soil region during 2010-2020

Soil temperature has a great influence on soil humification and mineralization, so it is of great significance to collect soil temperature observations at different spatial scales. Located in the core area of black soil, Hailun Agricultural Ecological Experiment Station (hereinafter referred to as Hailun Ecological Station) is a state-level long-term positioning research station of China Ecosystem Research Network. The soil temperature data of Hailun Ecological Station is of great significance for studying the soil water and heat process in black soil area. The data in this dataset are collected at Helen Ecological Station by the MILOS520 and MAWS301 automatic monitoring systems developed by VAISALA Company of Finland. We used the “Eco-meteorological Workstation” software process the observation data, and ensured the accuracy of the monitoring soil temperature data through analysis, inspection and reasonable optimization. This dataset consists of 11 data tables, namely the yearly soil temperature data of 11 years from 2010 to 2020, respectively. Each data table includes hourly soil temperature data of 0 cm, 5 cm, 10 cm, 15 cm, 20 cm, 40 cm, 60 cm and 100 cm. The publication of this dataset aims to provide scientific basis for the protection and long-term use of black soil.
