CO2-broadened water in the pure rotation and ν2 fundamental regions

MGS TES observations of the water vapor above the seasonal and perennial ice caps during northern spring and summer

“…Recent analysis of the CO 2 broadening of the water vapor rotational lines (Brown et al, 2007) supports the value for the broadening coefficient used in the calculation of water absorption here and in the original TES retrieval (Smith, 2002). Hence the error related to the choice of that parameter is much less than the original assumption of 25% (Smith, 2002).…”

The HITRAN 2004 molecular spectroscopic database

“…These data are an extensive set of calculations for D 2 O rotational band transitions extended to 6536 lines using the partner transition rule [58] . Using these data, a set of J -averaged half widths was determined for J = 0-50 [57] .…”

Mars’ water vapor mapping by the SPICAM IR spectrometer: Five martian years of observations

“…It is traditionally used for many applications in the Earth's atmosphere. And third, to account for the CO 2 broadening of water vapor lines in the Mars atmosphere, we adopt the broadening scale factor of 1.7, following Gamache et al (1995) and recent work by Brown et al (2007); i.e., we multiplied the air-broadened half-widths from the HITRAN 2004 database by 1.7. In the previous study a broadening factor of 1.3 was adopted.…”
