Abstract: It is shown, that existing methods of GPS measurements of total amount of precipitable water doesn’t accounted for regularities of variation of low clouds optical depth depending on latitude. The formulas for calculation of total amount of precipitable water during GPS measurements in condition of low clouds prevalence in dependence of latitude are given.

Keywords: total amount of precipitable water, wet delay, clouds, GPS measurements, atmosphere, optical depth.
