摘　　要：下垫面温度(地表温度)和不同深度的土壤温度统称地温,它的变化和变化规律是大气与陆地表面能量和物质交换的综合表征,因此地温是土壤热力状况的重要参量。四川盐亭农田生态系统国家野外科学观测研究站(简称盐亭站,代码YGA)位于亚热带四川盆地农业生态区,是中国生态系统研究网络(Chinese Ecosystem Research Network,CERN)和国家科技基础条件平台布局在该生态区域的农田生态系统试验观测与研究平台。本数据集是基于盐亭站综合气象观测场长期的自动站观测数据和人工观测数据整理计算而成,共包括4个数据文件,分别是自动站每日逐时地温数据(1997–2021)、自动站逐日地温统计数据(2004–2021)、自动站地温度月值统计数据(2004–2021)和人工观测地表温度日值与月值数据(2004–2021),数据量约8.85 MB。地温为野外台站联网观测指标,其观测仪器、数据获取过程和数据质控执行统一的相关规范和标准,确保地温数据的可靠性和可比性。长时间序列、多层次地温数据的积累,可为生态系统的能量物质交换、环境变化响应科学研究以及盆地农业主体区域在耕地质量评估和粮食安全方面的应用研究提供科学数据支撑。The underlying surface temperature(i.e.land surface temperature)and soil temperature at different depths are collectively referred to as ground temperature.The variations and variation rules of ground temperature comprehensively depict the exchange of energy and materials between the atmosphere and the land surface.Hence ground temperature is an important parameter for assessing soil thermal conditions.Located in the agro-ecological zone of subtropical Sichuan Basin,Sichuan Yanting Agro-ecosystem Research Station in Chinese National Ecosystem Research Network(also referred to as Yanting Station,code YGA)serves as an experimental observation and research platform of Agro-Ecosystem set by the Chinese Ecosystem Research Network(CERN)and the National Science and Technology Infrastructure Platform in this ecological region.This dataset is based on the long-term automatic station observation data and manual observation data of the comprehensive meteorological observation field of Yanting Station.It consists of four data files,namely,hourly ground temperature data from the automatic observation stations on a daily basis(1997-2021),daily ground temperature statistical data from the automatic observation stations(2004-2021),monthly statistical data of ground temperature from the automatic observation stations(2004-2021)and daily and monthly surface temperature data form the manual observation stations(2004-2021).The data volume is about 8.85 MB.Ground temperature is the networked observation index of field stations.Observation instruments,data acquisition procedures,and data quality control adhere to standardized norms and protocols,ensuring the utmost reliability and comparability of ground temperature data.The accumulation of long time series and multi-level geothermal data can provide scientific data support for the energy and material exchange of ecosystem,the response to environmental change,and the application research of cultivated land quality assessment and food security in the main agricultural areas of the basi
