We investigated the light-absorption properties of brown carbon (BrC) as part of the Georgia Wildland-Fire Simulation Experiment. We constructed fuel beds representative of three ecoregions in the Southeastern U.S. and varied the fuel-bed m...
Estimation and Applications of Uncertainty in Methane Emissions Quantification Technologies: A Bayesian Approach [0.03%]
基于贝叶斯方法的甲烷排放量化技术的不确定性估算及应用研究

Augustine Wigle et al.
An accurate understanding of uncertainty is needed to properly interpret methane emission estimates from upstream oil and gas sources in a variety of contexts, from component-level measurements to yearly jurisdiction-wide inventories. To ch...
Composition and Sources of Organic Aerosol in Two Megacities in Western China Using Complementary Mass Spectrometric and Statistical Techniques [0.03%]
利用互补质谱和统计技术解析中国西部两个超大型城市中有机气溶胶的组成及来源
