Daily estimates for meteorological and potential evapotranspiration variables (CHESS) and soil moisture estimates (JULES) at COSMOS-UK sites, 2013-2017

This dataset provides daily estimates at locations that are part of the COSMOS-UK monitoring network for meteorological and potential evapotranspiration variables in the Climate hydrology and ecology research support system for the period 2013-2017 (CHESS-met and CHESS-PE). Additionally, for the same period, it provides estimates at COSMOS-UK sites locations for soil moisture simulations provided by JULES (Joint UK Land Environment Simulator) at four layers: top layer (0.0-0.1 m depth), second layer (0.1-0.35 m depth), third layer (0.35-1 m depth) and bottom layer (1-3 m depth). The following variables are available in the dataset: daily temperature range (K), specific humidity (kg kg-1), precipitation (kg m-2 s-1), air pressure (Pa), downward longwave radiation (W m-2), downward shortwave radiation (W m-2), wind speed (m s-1), potential evapotranspiration (mm day-1) and potential evapotranspiration with interception correction (mm day-1), soil moisture content of 1-top layer (m depth), soil moisture content of 2-second layer (m depth), soil moisture content of 3-third layer (m depth) and soil moisture content of 4-bottom layer (m depth).

本数据集针对2013-2017年时段，基于气候水文与生态学研究支撑系统（Climate hydrology and ecology research support system，CHESS-met与CHESS-PE），为COSMOS-UK监测网络的站点提供气象变量与潜在蒸散发变量的逐日估算值。同期，本数据集还为COSMOS-UK站点提供由JULES（Joint UK Land Environment Simulator，英国联合陆地环境模拟器）生成的四层土壤湿度模拟估算值，四层分别为：表层（0.0~0.1 m深度）、第二层（0.1~0.35 m深度）、第三层（0.35~1 m深度）以及底层（1~3 m深度）。本数据集包含以下变量：日温差（K）、比湿（kg·kg⁻¹）、降水量（kg·m⁻²·s⁻¹）、气压（Pa）、向下长波辐射（W·m⁻²）、向下短波辐射（W·m⁻²）、风速（m·s⁻¹）、潜在蒸散发（mm·day⁻¹）以及带截留校正的潜在蒸散发（mm·day⁻¹）、1号表层土壤含水量、2号第二层土壤含水量、3号第三层土壤含水量与4号底层土壤含水量。
