摘　　要：太阳辐射控制着大气层、水圈、生物圈及岩石圈发生的各种生物作用、化学作用及其他作用。太阳辐射作为森林生态系统的热量和能量来源,是生态系统维持本身正常运转和发展的原始动力,对植物光合作用、蒸腾作用及生态系统碳交换等过程有重要的影响。贡嘎山地处青藏高原东南缘,在高山生态系统中具有典型性和代表性。按照中国生态系统研究网络(CERN)和国家生态系统观测研究网络(CNERN)统一规范,中国科学院贡嘎山高山生态系统观测试验站(简称贡嘎山站)开展了辐射长期监测工作。本数据集利用贡嘎山站自动辐射观测系统采集原始数据,经过数据处理、质量控制和评估,将1998–2018年的辐射数据,共计22个指标97 KB公开报道,为全球变化下高山生态系统碳循环、水循环和能量循环提供基础数据。Solar radiation governs biological,chemical and other processes in the atmosphere,hydrosphere,biosphere and lithosphere.As the source of heat and energy of forest ecosystem,solar radiation is the original power to maintain the normal operation and develop the ecosystem,and has important effects on plant photosynthesis,transpiration and carbon exchange.Gongga Mountain is located in southeast edge of Tibetan Plateau,and is a typical and representative alpine ecosystem.According to the protocols for standard radiation observation and measurement of Chinese Ecosystem Research Network(CERN)and National Ecosystem Research Network of China(CNERN),the Alpine Ecosystem Observation and Experiment Station of Gongga Mountain,Chinese Academic of Sciences has been carrying out long-term radiation monitoring practice.In this dataset,we report 22 radiation indices(total file size,97 KB)collected from the automatic radiation system after data processing and quality control and assessment during 1998–2018.The dataset can provide basic data for carbon cycle,water cycle and energy cycle of alpine ecosystem under global change.
