Atmospheric Composition Ammonia Volume Mixing Ratio L3 (AIRSAC3MNH3 V3) from AIRS/AMSU on NASA Aqua at GES DISC

The mass concentration ammonia in the atmosphere, consists of products generated for the study of atmospheric ammonia. Atmospheric ammonia is an important component of the global nitrogen cycle. In the troposphere, ammonia reacts rapidly with acids such as sulfuric and nitric to form fine particulate matter. These ammonium containing aerosols affect Earth's radiative balance, both directly by scattering incoming radiation and indirectly as cloud condensation nuclei. Major sources of atmospheric ammonia involve agricultural activities including animal husbandry, especially concentrated animal feeding operations and fertilizer use. Major sinks of atmospheric ammonia involve dry deposition and wet removal by precipitation, as well as conversion to particulate ammonium by reaction with acids. Measurements of ambient NH3 are sparse, but satellites provide a means to monitor atmospheric composition globally. Using the AIRS/AMSU satellite this algorithm provides monthly measurements of derived atmospheric NH3 for September 2002 through August 2016.

大气中的氨质量浓度，由用于大气氨研究产生的产物组成。大气氨是全球氮循环的重要组成部分。在对流层中，氨与硫酸和硝酸等酸性物质迅速反应，形成细颗粒物。这些含铵的气溶胶影响地球的辐射平衡，既通过散射入射辐射产生直接影响，也作为云凝结核产生间接影响。大气氨的主要来源包括农业活动，尤其是集约化畜牧业和肥料的使用。大气氨的主要汇包括通过降水进行的干燥沉积和湿去除，以及与酸性物质反应转化为颗粒态铵。环境中的氨测量数据稀少，但卫星提供了一种全球监测大气组成的手段。利用AIRS/AMSU卫星，该算法提供了从2002年9月到2016年8月的每月大气NH3推导值测量结果。
