他们做,但不是极端的$\ce{O3}$做。作为参考,地面附近有$\ce{O3}$,但平流层中的$\ce{O3}$被形成它的查普曼循环放大。

一般来说,温室气体在其产生的地层中浓度最高。让我们来思考一些(不是全部)温室气体,它们的来源,以及一些将它们限制在其层内的相关过程。

  • $\ce{CO2}$ -燃烧和呼吸排放。因为$\ce{CO2}$是一个非常稳定的分子,由于分子量的关系,在它掉下来之前,它可能会飞到相当高的大气层中。但由于它产生的地方,它仍然更集中在地面附近。< / p >

  • Water vapor (yes, it is a greenhouse gas) - most prominent in the surface layer, but generally decreases with height. Generally caps out due to phase transition (it becomes liquid water and ice), but some can enter into the stratosphere.

  • Methane - agricultural and biological sources. Like water, it is most prominent in the surface layer. However, it isn't as bound by phase transition as water vapor is. It does interact with other chemicals in the atmosphere, such as the hydroxyl radical.
