在$NH_3$-富和$NH_3$-贫的环境中,二次气溶胶的形成途径是不同的。例如,$NH_3$与$_2SO_4$结合后,如果$NH_3$是多余的,它们将继续与$HNO_3$反应生成$NH_4NO_3$。而在贫$NH_3$环境下,$HNO_3$会与地壳物质发生反应,形成粗态硝酸盐。
这样,$NH_3$的浓度水平影响了大气气溶胶的化学组成、尺寸分布。然而,$NH_3$的地面监测在中国仍然有限,在有限的地点发表了几次。
因此,我想知道:
有关于从卫星数据估计大气$\ mathm {NH}_3$的论文,例如here或here。但是,这些是用于列集成的,而不是用于曲面$\ mathm {NH}_3$。李< / p > < / > < / ol >
In general, you will see high NH3 near large sources like wildfires, livestock waste stockpiling, and crops with recent fertilizer application.
