You've got to chase the effects of pressure broadening through the complicated models that track the absorbtion and re-emission of infra-red radiation as it travels up through the atmosphere to get a real feel for the effect of pressure broadening - effectively the lower atmosphere is opaque to infra-red at the peaks of the water and carbon dioxide spectral lines, and pressure broadening widens these lines, blocking out more of the infra- red spectrum than you'd calculate from the textbook spectra taken measured on pure gases at low pressures" maybe we should tell bill about the Orbiting Carbon Observatory (OCO), and how he should read from the list of publications associated with the project http://oco.jpl.nasa.gov/index.cfm http://oco.jpl.nasa.gov/publications/project/ 2007 Aben, I., O.
