2019-2021中国典型生态系统通量观测站配套土壤环境数据集

本数据集包括4部分：（1）半小时尺度土壤环境数据，包括2019至2021年60个典型生态系统（森林、草地、荒漠、农田、湿地）通量观测站点的土壤温度、土壤热通量、3层剖面土壤含水量等土壤环境观测数据，经数据质量控制、校正和插补的半小时均值；（2）日尺度土壤环境数据，包括2019至2021年60典型生态系统（森林、草地、荒漠、农田、湿地）日尺度土壤环境观测数据，是在校正和插补后的半小时尺度数据基础上，计算得到的各观测指标的日均值、最大值和最小值数据；（3）月尺度土壤环境数据，包括2019至2021年60典型生态系统（森林、草地、荒漠、农田、湿地）月尺度土壤环境数据，是在日尺度数据基础上统计计算得到的各观测指标的月均值、最大值和最小值数据；（4）年尺度土壤环境数据，包括2019至2021年60典型生态系统（森林、草地、荒漠、农田、湿地）年尺度土壤环境数据，是在日尺度数据基础上统计计算得到的各观测指标的年均值、最大值和最小值数据。

This dataset comprises four components:
(1) Half-hourly soil environmental data: This includes half-hourly averaged soil environmental observations, namely soil temperature, soil heat flux, and three-layer profile soil water content, sourced from 60 flux observation sites across five typical ecosystems (forest, grassland, desert, cropland, wetland) during 2019–2021. All data have undergone quality control, calibration, and gap-filling procedures.
(2) Daily-scale soil environmental data: Derived from the calibrated and gap-filled half-hourly data, this component provides daily mean, maximum, and minimum values of each observed indicator for the 60 flux observation sites across the five aforementioned typical ecosystems from 2019 to 2021.
(3) Monthly-scale soil environmental data: Based on the daily-scale soil environmental data, this component includes monthly mean, maximum, and minimum values of each observed indicator, covering the 60 flux observation sites across the five typical ecosystems during 2019–2021.
(4) Annual-scale soil environmental data: Calculated from the daily-scale soil environmental data, this component consists of annual mean, maximum, and minimum values of each observed indicator for the 60 flux observation sites across the five typical ecosystems from 2019 to 2021.
