This is a list of LLGHG (long-lived greenhouse gases) greenhouse gases as used by the IPCC TAR.

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).
