生物质燃烧是颗粒物和微量气体的重要来源，也是陆地碳循环的一个主要因素。需要对植被火灾的排放进行严格限制，以模拟生物质燃烧气溶胶的直接和间接影响，模拟大气中的均相和非均相化学，并进行可靠的地球系统分析以及气候和空气污染研究。为了提高NASA戈达德地球观测系统模式（GEOS）在大气成分模拟方面的性能，重点是生物质燃烧，我们开发了快速火灾排放数据集（QFED）。QFED排放量是基于火辐射功率（自上而下）的方法，并借鉴了全球火同化系统（GFAS）中开发的云校正方法。火灾的位置和火灾辐射功率是由中分辨率成像光谱仪（MODIS）的二级火灾产品（MOD 14和MYD 14）和MODIS地理定位产品（MOD 03和MYD 03）获得的。QFED的优势是高空间和时间分辨率以及近实时可用性。日平均排放量为0.3125×0.25度，最近的版本也为0.1×0.1度。QFED提供黑碳、有机碳、二氧化硫、一氧化碳、二氧化碳、PM2.5、氨、氮氧化物、甲乙酮、丙烯、乙烷、丙烷、异丁烷、乙醛、甲醛、丙酮和甲烷的排放。美国航天局全球建模和同化办公室（GMAO）维护着两个QFED产品系统：一个系统产生在GEOS-5数据同化系统中实际使用的近实时日排放量，另一个系统产生2000年3月至今日排放量的扩展历史数据集。历史数据集还提供了月平均和月气候排放量。
Biomass burning is an important source of particulates and trace gases and a major element of the terrestrial carbon cycle. Well constrained emissions from vegetation fires are needed to model direct and indirect effects of biomass burning aerosols, to model homogeneous and heterogeneous chemistry in the atmosphere, and to perform credible Earth system analysis, and climate and air pollution studies. To improve the performance of NASA Goddard Earth Observing System Model (GEOS) in the areas of atmospheric constituent modeling with a focus on biomass burning we developed the Quick Fire Emissions Dataset (QFED). The QFED emissions are based on the fire radiative power (top-down) approach and draw on the cloud correction method developed in the Global Fire Assimilation System (GFAS). Location and fire radiative power of fires are obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) Level 2 fire products (MOD14 and MYD14) and the MODIS Geolocation products (MOD03 and MYD03). QFED strengths are high spatial and temporal resolutions and near-real time availability. Daily mean emissions are available at 0.3125×0.25 degrees and in recent versions also at 0.1×0.1 degrees. QFED provides emissions of black carbon, organic carbon, sulfur dioxide, carbon monoxide, carbon dioxide, PM2.5, ammonia, nitrogen oxides, methyl ethyl ketone, propylene, ethane, propane, nand i-butane, acetaldehyde, formaldehyde, acetone and methane. Two QFED product systems are maintained by the NASA Global Modeling and Assimilation Office (GMAO): one that produces near real-time daily emissions used operationally in the GEOS-5 Data Assimilation System, and one that produces an extended historical dataset with daily emissions from March 2000 to the present. The historical dataset also provides monthly mean and monthly climatological emissions.
