Comparative Ecosystem Analysis Using Inverse Parameter Retrieval

在地球仪的森林中有100多个监测点，持续测量森林与大气之间的二氧化碳交换速率和幅度，其中一些监测点的测量时间现在接近或超过10年。 生态系统过程的计算机模型，重点是光合作用和呼吸作用，将用于评估来自20个森林监测点的数据，以便比较评估哪些森林最有可能影响大气CO2浓度，以及为什么。了解导致大气CO2积累的过程，从而对未来气候变暖的影响，需要我们了解地球仪上的森林生态系统如何与大气交换二氧化碳，并最终将部分二氧化碳封存在森林的树木和土壤中。 这项研究将促进新的计算机建模方法的发展，适用于CO2通量监测站点，包括那些在一个新兴的国家网络的环境监测站点被称为国家生态观测站网络（氖）。

There are over 100 monitoring sites in forests across the globe that continuously measure the rate and magnitude of CO2 exchange between the forest and atmosphere, and some of these sites are now approaching, or have exceeded, ten years of measurements. Computer models of ecosystem processes, focusing on those involved with photosynthesis and respiration, will be used to evaluate the data from 20 of these forest monitoring sites in order to comparatively evaluate which forests have the highest potential to affect the atmospheric CO2 concentration, and why.An understanding of the processes that result in the accumulation of atmospheric CO2 and thus, impacts to future climate warming, require that we understand how forest ecosystems across the globe exchange CO2 with the atmosphere, and ultimately sequester some of the CO2 in the trees and soils of the forest. The research will facilitate the development of new computer modeling approaches to be applied to CO2 flux monitoring sites including those in an emerging national network of environmental monitoring sites known as the National Ecological Observatory Network (NEON).
