A Multi-Layer Model of Carbon Dioxide

I have put together a simple multi-layer model of  carbon dioxide in the troposphere.  It is based upon the same principles as the two-layer model and the three-layer model.  It accounts for the temperature and pressure profiles from the  previous post and it is part of a primer on infrared spectroscopy and global warming.  Just like those other models there are still caveats; this model is intended to be illustrative of concepts and therefore it is conceptually simple.

Structure of the Atmosphere

This post is part of a primer on infrared spectroscopy and global warming. The previous post introduces a three-layer model  in the context of developing a radiative-transfer model of the atmosphere.  From that post it should be apparent that one needs to include an understanding of the structure of the atmosphere to understand radiative transfer through the atmosphere. This post provide a summary of the structure of the atmosphere.  It is intended to be a quick introduction, rather than a detailed treatise.  Some of the sources listed go into more detail for the interested reader.
