The pressure is set to 1 atm and the temperature to 296 K. … Web10th HITRAN Database Conference Calculations The 2004 HITRAN database contains some 251 440 methane transitions. Considering only bands of 12CH 4 between 9 and 1.6 μm with the sum of line intensities greater than 10-20 cm-1/(molecule·cm-2) yields a list of over one hundred thousand transitions. Here, we focus on the region 2726 to 3200 cm-1,

Web5 set 2014 · For CH4, we find that near-infrared absorption is much stronger than previously thought, arising from updates to the HITRAN database. CH4 radiative forcing peaks at 10.3, 9, or 8.3 Wm-2 for background pressures of 0.5, 1 or 2 bar, likely limiting the utility of CH4 for warming the Archean.
