Total radiative forcing (TRF) functions for CH4 and CO2 used in calculation of TWP in Eq. 2 for three distinct emissions profiles
| Case | TRFCH4(t) | TRFCO2(t) |
| Pulse TWP | RE{τM(1 - e-t/τM)} |  |
| Service Life TWP for t≤ AMAX |  |
 |
| Service Life TWP for t > AMAX |  |
 |
| Fleet Conversion TWP |  |
 |
RE in these formulas is the radiative efficiency of CH4 relative to CO2 and equals 102.
