AmeriFlux AmeriFlux US-xSJ NEON San Joaquin Experimental Range (SJER)

This is the AmeriFlux version of the carbon flux data for the site US-xSJ NEON San Joaquin Experimental Range (SJER). Site Description - Located at The San Joaquin Experimental Range, in the western foothills of the Sierra Nevada, this 18.2 kilometer terrestrial field site is a mix of open woodlands, shrubs and grasslands with low density cattle grazing. SJER is an ecosystem research experimental area. It was originally conceived as a cooperative interdisciplinary research center to identify cost-effect methods of commercial livestock production in the annual grass-oak pine woodlands, while maintaining the integrity of the ecosystem. More recently, research objectives have expanded and diversified to include research projects making contributions to our knowledge of the patterns and processes working in this ecosystem.

本数据集为站点US-xSJ NEON圣华金实验牧场（SJER）的美国通量网（AmeriFlux）版碳通量数据。站点概况——本场地坐落于内华达山脉西部山麓的圣华金实验牧场，这片占地18.2千米的陆地野外研究样地为开阔林地、灌丛与草原的混合生态系统，辅以低密度肉牛放牧活动。SJER是一处生态研究实验区域，其最初的设立初衷是打造跨学科合作研究中心，旨在在一年生草本-栎松混交林地中探索兼具成本效益的商业化畜牧生产方案，同时维持该生态系统的完整性。近年来，其研究目标得到拓展与多元化，新增了多项旨在深化对该生态系统运行模式与过程机制认知的研究课题。
