Abstract : The relationship between the total precipitable water in the atmosphere, and surface absolute humidity has been examined for more than 1500 upper-level soundings. Total precipitable water and surface absolute humidity were computed for all of the upper-level soundings made in 1970 at San Nicolas Island, Point Mugu, and China Lake, California. The stations, separated by less than 200 mi, are representative of a maritime, a coastal, and a desert environment, respectively. The monthly correlation coefficients, ranging from -0.25 to +0.89, indicate that a direct but widely variable relationship exists between the total precipitable water and surface absolute humidity; however, these results also demonstrate that estimates of total precipitable water from surface humidity measurements are not valid.
