I post the latter part of this as simply reference for people. Much of Atmospheric Science text does not seem to be easily accessible on the internet. I will continue to post to this thread information that I've come to understand from my studies of Atmospheric science. All of the tables will be verifiable text-book models by an unbias publisher. Links to Articles Discussing Solar System Warming: Jupiter Mars Mars Pluto =================== Concentration of Aitken particles in #/cm^3: Code: Region: Average: Average Range: City 147,000 49,100-379,000 Town 34,300 5,900-114,000 Countryside 9,500 1,050-66,500 Mountain (2km) 950 160-5,300 Islands 9,200 460-43,600 Oceans 400 100-1,000 Size Classes of aerosol Particles: Code: Class: Range of Radii (micrometer) Small Ions 5-8 e-4 Large Ions 1.5e-3 to 1e-1 Aitken Particles 1.5e-3 to 1e-1 Haze Particles .1-1 Cloud Condens Nuclei 1e-2 to 20 Large Condens Nuclei .1-1 Giant '' 1-20 Particles containing most of aerosol mass 5e-2 - 20 Size Distribution of the Continental Aerosol \(\frac{dN}{d(ln(r))} = cr^{-v}\) c = constant related to total concentration of aerosol particles. N = total concentration of particles smaller than radius r per unit of volume of air Objective analysis has shown v to be variable between 2.5 and 3.5 There are more precise equations than this if someone would like to know them, the former was relatively acceptable average. =================== These estimates were 1960-1980's estimates of atmospheric content. There no commentary in my Physical Meteorology nor Atmospheric Chemistry of idealized distributions. If anyone is either aware of idealized models, or, variations in these figures. Feel free to comment.
