Water vapors in atmosphere are one of major components causing «greenhouse effect». Water vapors play an important role in energetic balance of atmosphere and significantly decrease the transmission of atmosphere in different zones of electromagnetic spectrum. All above mentioned proves importance of development of new methods for measuring of water papers in atmosphere.
One of widely used methods for measuring od water vapours in atmosphere is method of utilization of sun photometers. This article is devoted to the suggested technique for increase of accuracy of multiwavelength method of measuring of total amount of water vapours in atmosphere using sun photometers. The held researches have shown that non-stability of measuring results caused by hydrophilic component of aerosol is two times more than that of hydrophobic component which proves the potential feasibility to increase the accuracy of three wavelength method for measuring of water vapors using sun photometers by way of removal of effect of hydrophilic component. In order to remove the influence of hydrophilic component the relative parameter, depending on results of measurements at three wavelengths of absorption of water vapors is formulated. The unique linear model of effect of water vapors on optical depth of atmospheric aerosol is formed. The new three wavelengths methodic for measuring of water vapors in atmosphere is suggested, where the non-stabilizing effect of hydrophilic component of atmospheric aerosol is removed. The algebraic equation is derived solution of which make it possible to determine total amount of water vapors in atmosphere removing effect on non stable factors existing in known models. The model estimate for increase of accuracy in suggested method is given.
