森林通过碳储存和吸收对减缓气候变化作出贡献，但这种碳库在空间和时间上的变化程度仍然知之甚少。几个地球观测任务已经专门设计来解决这个问题，例如，NASA的GEDI， NASA - ISRO的NISAR和ESA的生物质。然而，所有这些任务的产品都需要独立和一致的验证。因此，需要一个永久的、全球性的、就地的、基于立地的森林生物量参考测量系统，该系统依赖于尽可能高质量的地面数据。在这里，我们通过对文献和专家知识的深入回顾，汇集了近200个高质量网站的列表。在这项研究中，我们探讨了这些遗址在环境条件、地理空间和与生物量相关的森林结构的覆盖方面与世界范围内的森林相比有多大的代表性。这项工作还旨在确定哪些地点最具代表性，以及在何处投资以提高拟议系统的代表性。我们表明，在至少175个最具代表性的地点被包括在内之后，该系统的环境覆盖率似乎没有改善，但随着更多地点的加入，地理和结构覆盖率继续改善。我们强调环境、地理或结构覆盖差的地区，包括但不限于加拿大、美国西半部、墨西哥、巴塔哥尼亚、安哥拉、赞比亚、俄罗斯东部以及热带和亚热带高地（如哥伦比亚、喜马拉雅山、婆罗洲、巴布亚）。为了使拟议的系统取得成功，我们强调：(1)必须在所有国家和大洲采用相同的标准收集和处理数据；(2)制度的建立和管理必须包容和公平，并认真考虑工作条件；(3)培训和现场合作伙伴参与下游活动应该是强制性的。需要一个永久的、全球性的、基于现场的森林生物量参考测量系统，该系统依赖于尽可能高质量的地面数据，以验证与生物量相关的地球观测任务的产品。在这里，我们汇集了近200个高质量网站的列表。与世界各地的森林相比，我们探讨了这些遗址在环境条件、地理空间和与生物量相关的森林结构方面的代表性。
Forests contribute to climate change mitigation through carbon storage and uptake, but the extent to which this carbon pool varies in space and time is still poorly known. Several Earth Observation missions have been specifically designed to address this issue, for example, NASA's GEDI, NASA‐ISRO's NISAR and ESA's BIOMASS. Yet, all these missions' products require independent and consistent validation. A permanent, global, in situ, site‐based forest biomass reference measurement system relying on ground data of the highest possible quality is therefore needed. Here, we have assembled a list of almost 200 high‐quality sites through an in‐depth review of the literature and expert knowledge. In this study, we explore how representative these sites are in terms of their coverage of environmental conditions, geographical space and biomass‐related forest structure, compared to those experienced by forests worldwide. This work also aims at identifying which sites are the most representative, and where to invest to improve the representativeness of the proposed system. We show that the environmental coverage of the system does not seem to improve after at least the 175 most representative sites are included, but geographical and structural coverages continue to improve as more sites are added. We highlight the areas of poor environmental, geographical, or structural coverage, including, but not limited to, Canada, the western half of the USA, Mexico, Patagonia, Angola, Zambia, eastern Russia, and tropical and subtropical highlands (e.g. in Colombia, the Himalayas, Borneo, Papua). For the proposed system to succeed, we stress that (1) data must be collected and processed applying the same standards across all countries and continents; (2) system establishment and management must be inclusive and equitable, with careful consideration of working conditions; and (3) training and site partner involvement in downstream activities should be mandatory. A permanent, global, in situ, site‐based forest biomass reference measurement system relying on ground data of the highest possible quality is needed to validate products from biomass‐related Earth Observation missions. Here, we have assembled a list of almost 200 high‐quality sites. We explore how representative these sites are in terms of their coverage of environmental conditions, geographical space and biomass‐related forest structure, compared to those experienced by forests worldwide.
