Present Composition of the Atmosphere. The atmosphere is comprised of gases which are considered to be permanent (gases which remain essentially constant by percent) and gases considered to be variable (gases which have changing concentrations over a finite period of time). PERMANENT gases in the atmosphere by percent are: Nitrogen = 78.1%; Oxygen = 20.9%. Note that these two permanent gases together comprise 99% of the atmosphere. Other permanent gases: Argon = 0.9%; Neon = 0.002%; Helium = 0.0005%; Krypton = 0.0001%; Hydrogen = 0.00005%. VARIABLE gases in the atmosphere and typical percentage values are: Water vapor = 0 to 4%; Carbon Dioxide = 0.035%; Methane = 0.0002%; Ozone = 0.000004%.  5, record 3, English, - composition%20of%20the%20atmosphere

La composition de l'atmosphère est assez hétérogène. La masse principale est constituée par un mélange gazeux, l'air sec, auquel s'ajoutent une très faible proportion d'aérosols ainsi que de l'eau soit sous forme condensée (liquide ou solide) soit à l'état de vapeur. Ainsi sur les dix tonnes qui représentent à peu près la masse de l'atmosphère au-dessus d'un même carré de sol, au niveau moyen de la mer, il y a 9,98 tonnes d'air, un peu moins de 20 kilogrammes d'eau (soit l'équivalent de 20 mm d'eau pluviale) et environ un kilogramme de matériaux solides divers très finement divisés dont une très faible partie de micro-organismes.  4, record 3, French, - composition%20de%20l%26rsquo%3Batmosph%C3%A8re

What determines the chemistry of rain and snow? The water comes from evaporation and transpiration (water vapor lost by plants) and is essentially distilled, or pure. Once the vapor reaches the atmosphere, however, it condenses on solid particles and soon reaches equilibrium with atmospheric gases. One of the gases is carbon dioxide (CO2), and as carbon dioxide dissolves in the water carbonic acid (H2CO3) forms. Carbonic acid, being a weak acid, dissociates only slightly in distilled water, yielding hydrogen ions and bicarbonate ions (HCO3-). At normal concentrations and pressures of carbon dioxide in the atmosphere the pH of rain and snow would be 5.6.  1, record 15, English, - chemistry%20of%20snow
