Atmospheric Composition Ammonia Volume Mixing Ratio L3 (AIRSAC3MNH3 V3) from AIRS/AMSU on NASA Aqua at GES DISC
简介
大气中氨的质量浓度由用于研究大气氨的生成物组成。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快速反应形成细颗粒物。这些含氨气溶胶会影响地球的辐射平衡，既直接影响入射辐射，也间接影响云凝结核。大气氨的主要来源包括农业活动，包括畜牧业，尤其是集约化动物饲养和化肥使用。大气氨的主要汇包括干沉降和降水的湿迁移，以及与酸反应转化为颗粒氨。大气中氨的测量值很少，但卫星提供了一种监测全球大气成分的方法。该算法利用 AIRS/AMSU 卫星，提供 2002 年 9 月至 2016 年 8 月期间每月大气氨的测量值。
