Title: Sunset 
 
Description: 
 
This cross section of the Earth's atmosphere at sunset and earth limb 
(24.5S,  43.5E) displays an unusual layering believed to be caused by 
temperature  inversions which effectively concentrate smoke, dust and 
aerosols into narrow  layers.  the top of the stratosphere can be seen as 
the top of the white  layer thought to contain volcanic debris.  The purple 
layer is the  troposphere containing smoke from landclearing biomass 
burning.
