A method is developed that allows the construction of spatial emission inventories. The method is applied for anthropogenic SO over China (0.25°×0.25°). The Enhancement Ratio Method (ERM) allows for the calculation of SO emissions using relationships between gridded satellite measurements of SO and NO at low wind speeds, and satellite-based NOx emission estimates. Here, we derive SO emissions for five years (2007-2011). A large decrease of emissions during 2007-2009 and a modest increase between 2010 and 2011 is observed. The evolution of emissions over time calculated here is in general agreement with bottom-up inventories, although differences exist, not only between the current inventory and other inventories but also among the bottom up inventories themselves. The ERM-derived emissions are consistent, spatially and temporally, with existing inventories.
开发了一种方法，可用于构建空间排放清单。该方法应用于中国人为 SO（0.25°×0.25°）。增强比方法（ERM）允许使用低风速下网格化卫星测量的 SO 和 NO 之间的关系以及基于卫星的 NOx 排放估算来计算 SO 排放。在这里，我们推算了五年（2007-2011）的 SO 排放量。观察到 2007-2009 年排放量大幅下降，2010-2011 年略有增加。此处计算的排放随时间的演变总体上与自下而上的清单一致，尽管存在差异，不仅当前清单与其他清单之间存在差异，而且自下而上的清单本身之间也存在差异。ERM 衍生的排放量在空间和时间上与现有清单一致。
