WebEarly composition. The most critical parameter pertaining to the chemical composition of an atmosphere is its level of oxidation or reduction. At one end of the scale, an atmosphere rich in molecular oxygen (O 2 )—like Earth’s present atmosphere—is termed highly oxidizing, while one containing molecular hydrogen (H 2) is termed reducing.

WebWe define the “atmospheric lifetime” of a chemical in the atmosphere as follows: if we add an increment of that chemical to the atmosphere so that its concentration increases from x kg/m 2 to ( x + y) kg/m 2, then the atmospheric lifetime is the time it would take for the concentration of that chemical to decrease back to ( x + ye−1) kg/m 2.
