Water-Energy-Crop Observations (2015-2021) in Saskatchewan, Canada|农业环境观测数据集|作物生长数据集

Beginning in 2015, field observations were initiated to quantify crop growth and land-atmosphere energy and water exchanges over agricultural surfaces in the semi-arid south central Saskatchewan prairies. Early research focussed on sites in the Brightwater Creek Research Basin (BWC) near Kenaston, 80 km south of Saskatoon, Saskatchewan (Tetlock et al., 2019). Additional sites were instrumented in 2018 at the University of Saskatchewan’s Livestock and Forage Centre for Excellence (LFCE) near Clavet, 30 km southeast of Saskatoon, Saskatchewan. Cumulatively this data collection effort comprises 17 site years for 7 different crop types. This dataset is comprised of micrometeorological, energy balance (radiation and turbulent fluxes), precipitation, soil moisture and crop growth observations aggregated to the daily scale. Stations were located within agricultural fields to satisfy the homogeneity assumptions required for eddy covariance observations and span the interval between planting and harvest. Data gapfilling and QA/QC procedures are described in the associated submitted manuscript.

自2015年起，为量化农作物生长以及农业地表与大气之间的能量和水交换，开始了实地观测。初期研究集中于位于萨斯喀彻温省萨斯卡通市以南80公里处的肯斯塔顿附近的Brightwater Creek研究区（BWC）（Tetlock等，2019年）。2018年，在萨斯喀彻温大学Livestock and Forage Centre for Excellence（LFCE）附近，即萨斯卡通市东南30公里处的克劳维特，增设了额外的观测站点。此次数据收集工作总计涵盖了17个站点年，针对7种不同的作物类型。该数据集包括微气象学、能量平衡（辐射和湍流通量）、降水、土壤湿度和作物生长观测数据，这些数据均汇总至日尺度。观测站点位于农田内部，以满足涡度相关观测所需的同质性假设，并跨越了播种至收获的整个周期。数据填补和质控/质量保证（QA/QC）流程在相关提交的论文中有所描述。
