PURE WATER VAPOR ABSORPTION MEASUREMENTS IN 6.3 MICRON BAND

Author Institution: National Environmental Satellite Center, National Oceanic and Atmospheric Administration; Astronomy Research Facility, University of MassachusettsSeven strong isolated lines in the pure water vapor absorption band at 6.3$\mu$ have been measured at low pressures (1-3 mm of Hg) in the ONR 100-foot absorption cell with a path length of 93 meters, about one-half the path length of previous observations by Prinz. Different methods for determination of equivalent widths have been investigated and used to calculate strength-half-width products
