Space-based remote sensing can make an important contribution toward monitoring greenhouse gas emissions and removals from the agriculture, forestry, and other land use (AFOLU) sector, and to understanding and addressing human-caused climate change through the UNFCCC Paris Agreement. Space agencies have begun to coordinate their efforts to identify needs, collect and harmonize available data and efforts, and plan and maintain a long-term roadmap for observations. International cooperation is crucial in developing and realizing the roadmap, and the Committee on Earth Observation Satellites (CEOS) is a key coordinating driver of this effort. Here, we first identify the data and information that will be useful to support the global stocktake (GST) of the Paris Agreement. Then, the paper explains how existing and planned space-based capabilities and products can be used and combined, particularly in the land use sector, and provides a workflow for their harmonization and contribution to greenhouse gas inventories and assessments at the national and global level.
天基遥感可为监测农业、林业和其他土地利用（AFOLU）部门的温室气体排放与清除情况做出重要贡献，并通过《联合国气候变化框架公约》巴黎协定助力理解和应对人为气候变化。各航天机构已开始协调行动，以确定需求、收集和整合现有数据与工作，并规划和维护长期观测路线图。国际合作对于制定和落实该路线图至关重要，而地球观测卫星委员会（CEOS）是这项工作的关键协调推动者。在此，我们首先确定有助于支持巴黎协定全球盘点（GST）的数据和信息。然后，本文解释了如何利用和整合现有及计划中的天基能力与产品，特别是在土地利用部门，并提供了一个工作流程，用于协调这些能力与产品，并使其为国家和全球层面的温室气体清单及评估做出贡献。
