Atmospheric gases are the gases that make up the air of the earth's atmosphere. The atmosphere extends from the earth's surface to about 800 miles above the surface of the earth.

A breakdown of the composition from Wikipedia:

Nitrogen (N2)780,840 ppmv (78.084%)Oxygen (O2)209,460 ppmv (20.946%)Argon (Ar)9,340 ppmv (0.9340%)Carbon dioxide (CO2)390 ppmv (0.039%)Neon (Ne)18.18 ppmv (0.001818%)Helium (He)5.24 ppmv (0.000524%)Methane (CH4)1.79 ppmv (0.000179%)Krypton (Kr)1.14 ppmv (0.000114%)Hydrogen (H2)0.55 ppmv (0.000055%)Nitrous oxide (N2O)0.3 ppmv (0.00003%)Carbon monoxide (CO)0.1 ppmv (0.00001%)Xenon (Xe)0.09 ppmv (9 × 10−6%)Ozone (O3)0.0 to 0.07 ppmv (0% to 7 × 10−6%)Nitrogen dioxide (NO2)0.02 ppmv (2 × 10−6%)Iodine (I)0.01 ppmv (1 × 10−6%)Ammonia (NH3)traceNot included in above dry atmosphere:Water vapor (H2O)~0.40% over full atmosphere, typically 1%-4% at surface
