“温室气体”，特别是二氧化碳，与气候变化密切相关。为了了解气候系统的未来演变，并找到管理大气二氧化碳浓度的方法，必须首先了解驱动碳循环的过程和反馈。然而，我们目前对空间和时间模式的了解是不确定的，特别是在陆地和对变化可能高度敏感的地区，如北方地带。欧洲空间局（欧空局）全球碳项目旨在产生完全校准的陆地产品估计数，这些估计数与原始地球观测源几乎无关，主要用于动态全球植被模型，但也作为对全球碳项目的贡献，该项目是国际地圈生物圈方案、国际人文因素计划和世界气候研究计划，以帮助了解全球碳循环。这项服务的特点是估计全球燃烧面积、吸收的光合有效辐射比例、叶面积指数和植被生长周期。该演示器将集中于1998年至2007年的整整十年，届时欧空局地球观测传感器与其他协同传感器之间存在重叠。然而，该系统将是灵活的，因此它不依赖于任何单一的卫星传感器，因此可以追溯性地应用于现有的档案，并与未来的卫星传感器一起使用。
'Greenhouse gases', especially carbon dioxide, are intimately connected to climate change. To understand the future evolution of the climate system and find ways to manage the concentration of atmospheric carbon dioxide, the processes and feedbacks that drive the carbon cycle must first be understood. However, our current knowledge of spatial and temporal patterns is uncertain, particularly over land and in regions of potentially high sensitivity to change like the boreal zone. The European Space Agency (ESA) GLOBCARBON project aims to generate fully calibrated estimates of at-land products quasi-independent of the original Earth Observation source for use primarily in Dynamic Global Vegetation Models, but also as a contribution to the Global Carbon Project, a cooperation between the International Geosphere Biosphere Programme, International Human Dimensions Programme and the World Climate Research Programme to aid understanding of global carbon cycling. The service will feature estimation of global burned area, the fraction of absorbed photosynthetically active radiation (fAPAR), leaf area index (LAI) and Vegetation Growth Cycle. The demonstrator will focus on ten complete years, from 1998 to 2007 when overlap exists between ESA Earth Observation sensors and others that are synergistic. However, the system will be flexible so that it is not dependent on any single satellite sensor and therefore can be retrospectively applied to existing archives and used with future satellite sensors.
