科学领域:

环境科学环境科学
大气化学大气化学
气候变化研究气候变化研究

背景情况:

温室气体库存对于"巴黎协定"的透明度至关重要.
将库存与大气数据进行比较,可以识别不确定性并提高准确性.

研究的目的:

创建一个高分辨率 (0.1°×0.1°) 的美国人为甲排放 (2012-2018) 的网格清单.
为了使国家温室气体库存和大气观测之间进行可靠的比较.

主要方法:

制定了2012-2018年年度甲排放的网格清单,分为26个来源类别.
纳入了依赖规模的错误估计和美国环境保护局 (EPA) 美国温室气体排放和汇集 (GHGI) 数据的库存.
将网格数据与EDGAR版本6进行比较,并注意到石油和天然气行业的显著空间差异.

主要成果:

该清单与2020年EPA GHGI保持一致,反映了更新的活动和排放因素.
在所有来源中观察到甲排放的显著空间和时间变化.

Mass Spectrum

Mass Spectrum

A mass spectrum is the graphical representation of the relative abundance of the charged fragments in an analyte plotted against their mass-to-charge ratio (m/z). The plot's x axis represents the ratio of the mass of the charged fragment to the elementary charge it carries. The y axis of the plot represents the relative abundance of each charged species. The relative abundance is calculated from the signal intensity of each charged species recorded at the detector. The most intense signal...

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
