TEMPERATURE DEPENDENCE OF AIR-BROADENED LINE WIDTHS AND SHIFTS OF WATER AT $6 {\mu}m$

Air-broadened half-widths and pressure-induced frequency shifts of water vapor were derived from laboratory measurements using the McMath-Pierce Fourier transform spectrometer located at Kitt Peak. The observations were obtained at gas sample temperatures ranging from ${\sim} 241$ K to ${\sim} 388$ K for rotational transitions in the (000)-(000), (010)-(000), and (020)-(010) bands of water. Width and shift coefficients were determined for ${\sim} 500$ lines, and the temperature dependence of these coefficients was determined for most of the transitions $measured.^{a}$
