NO. 3 RADIATION OF THE ATMOSPHERE ANGSTROM \J 



But it has been shown by many elaborate investigations that, on 

 an average, we are able, with a certain amount of accuracy, to draw 

 conclusions about a large part of the atmosphere from observations 

 on a limited part of it. This will be further discussed in a chapter 

 on the distribution of water vapor and temperature conditions. The 

 discussion of the observations will therefore be founded upon mean 

 values, and will lead to a knowledge of average conditions.
