Abstract
Six years of spectroscopic measurements of the atmospheric line of H2O at 1.0832 μm are reported. The equivalent width of this line shows a stationary seasonal dependence corresponding to the range 4 to 27 mm precipitable water vapor in the monthly means. The extremes are 1.3 and 32 mm p.w.v. or a factor of 25. Inferred spectroscopic water vapor for Kitt Peak compares well with meteorological Rawinsonde data from nearby Tucson. The water vapor over certain other sites of current interest are then deduced from appropriate Rawinsonde records. A method for unblending a solar line contaminated by weak H2O blends is also given.Keywords
