Gases relevant to radiative forcing only (per IPCC documentation)

The following table has its sources in Chapter 2, pg 141, Table 2.1. of the IPCC Fourth Assessment Report, 2007.^[1]

Mole fractions: μmol/mol = ppm = parts per million (10⁶); nmol/mol = ppb = parts per billion (10⁹); pmol/mol = ppt = parts per trillion (10¹²).
