Monthly mean atmospheric precipitable water data for eighty-two sites in th continental US and Alaska have been analyzed to develop methods for accurately estimating precipitable water at sites where it has not been measured. Monthly mean precipitable water can be estimated with an rms error of about 12%, using the monthly mean surface temperature and relative humidity. This rms error can be reduced to about 7%, if the properties of the average atmospheric and surface conditions in the region surrounding the site are used. The amount of sunlight scattered by the atmosphere is a function of the amount of precipitable water and other quantities.
