摘　　要：太阳辐射是驱动碳水通量和其他各类陆面过程的重要参数之一。辐射表是测量局域尺度辐射和反照率最常用的仪器,气象观测标准为水平安装,但在坡面地形条件下其半球视角与下垫面接收或者反射辐射平面并不垂直,这种误差通常会导致净辐射与湍流能量通量之间存在日变化相位偏移。山区地带占全球陆表总面积的四分之一,然而很少有研究量化和校正山区地带采用水平安装净辐射表测量所产生的误差。本数据集整理了黑龙江帽儿山森林生态系统国家野外科学观测研究站天然次生林2016年3月17日至2017年4月3日的水平与坡面平行辐射表测量太阳辐射组分及湍流能量通量数据,包括入射与反射的短波辐射、长波辐射、光合有效辐射以及反照率、太阳高度角、晴空指数、感热通量、潜热通量、土壤表面热通量数据,为半小时时间尺度存储数据文件,生长季(2016年5月3日至10月10日)辐射数据和湍流能量通量数据覆盖率分别为100%和81.3%。本数据可以为评估辐射表安装方式对山区地带辐射分量和反照率测量的影响提供原始数据,不仅有助于修正历史数据或构建更准确的模型,还可为碳、水、能量通量相关研究提供方法参考。Solar radiation is one of the key parameters driving carbon and water fluxes,as well as other types of terrestrial processes.Radiometers,the most commonly used instruments for measuring local-scale radiation and albedo,are typically installed horizontally according to meteorological observation standards.However,under sloping terrain conditions,their hemispherical view and the surface receiving or reflecting radiation are not vertical.This discrepancy often results in a daily phase shift between net radiation and turbulent energy fluxes.Montane region accounts for one-quarter of the total global land surface area,yet few studies have quantified and corrected the errors resulting from horizontal installation of net radiometers in these areas.The dataset compiled in this paper were solar radiation and turbulent energy flux data measured by horizontal and slope-parallel radiometers in the secondary forest of the Maoershan Forest Ecosystem Research Station in Heilongjiang from March 17,2016,to April 3,2017.The data included incident and reflected shortwave radiation,longwave radiation,photosynthetically active radiation,as well as albedo,solar elevation angle,clear sky index,sensible heat flux,latent heat flux,and soil surface heat flux data.These data were stored in half-hour intervals,with radiation and turbulent energy flux data coverage rates during the growing season(May 3,2016 to October 10,2016)of 100%and 81.3%respectively.This dataset can provide original data for evaluating the impact of radiometers installation methods on the measurement of radiation components and albedo in montane regions,which not only help to correct historical data or construct more accurate models,but can also provide methodological references for studies related to carbon,water,and energy fluxes.
