追踪甲烷的来源和全球的移动

NASA’s new three-dimensional portrait of methane, the world’s second-largest contributor to greenhouse warming, shows it arising from a diversity of sources on the ground and how it moves through the atmosphere. Combining multiple data sets from emissions inventories, including fossil fuel, agricultural, biomass burning and biofuels, and simulations of wetland sources into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas and its role in Earth’s carbon cycle, atmospheric composition, and climate system.

甲烷是造成温室效应的第二大因素，美国国家航空航天局（NASA）最新发布的甲烷三维图像显示，甲烷显示甲烷是由地面上各种不同的来源产生，以及甲烷如何在大气中运动。将来自排放清单的多个数据集（包括化石燃料，农业，生物质燃烧和生物燃料，以及对湿地源的模拟）组合到高分辨率计算机模型中，研究人员现在有了一个额外的工具来了解这种复杂气体及其在地球碳循环、大气组成和气候系统中的作用。
