RCN: The FLUXNET Global Network Assessing Spatial-Temporal Variability of Carbon Dioxide, Water Vapor and Energy Fluxes Between the Terrestrial Biosphere and Atmosphere

这个名为FLUXNET的全球网络利用涡动相关法测量植被与大气之间的二氧化碳、水蒸气和能量交换，研究植被的呼吸。目前，在Ameriflux、CarboEuroflux、AsiaFlux和ChinaFlux等区域网络的主持和支持下，涡旋通量和一套气象、土壤和植物变量正在全球300多个地点进行测量。FLUXNET的作用是将分布式网络集成和统一为一个全球网络。作为一个整体，FLUXNET扩展了与其组成区域网络相关的生物群落、气候区域、干扰和土地利用处理的多样性。该网络产生的数据将用于检验许多问题。这些测量和综合与了解气候变化的影响和评估减缓从陆地到大气的碳通量增加的努力高度相关。它提供了一个衡量哪些地区在吸收碳，哪些地区在向大气中流失碳的方法。

The global network, called FLUXNET, studies the breathing of vegetation by measuring the exchange of carbon dioxide, water vapor and energy between vegetation and the atmosphere with the eddy covariance method. At present, eddy fluxes and a suite of meteorological, soil and plant variables, are being measured at over 300 sites world-wide, through the auspices and support of regional networks like Ameriflux, CarboEuroflux, AsiaFlux and ChinaFlux. FLUXNET plays the role of integrating and uniting the distributed networks into a global network. When combined as a group, the FLUXNET expands the diversity of biomes, climate regions, disturbance and land use treatment that are associated with its constituent regional networks. The data produced by the network will be used to examine many questions.The measurements and synthesis are highly relevant to understanding implications of climate change and evaluating efforts to mitigate increasing carbon flux from the land to the atmosphere. It provides a measure of which areas are sequestering carbon and which are losing carbon to the atmosphere.
