The paper analyses the long series of measurements of atmospheric variations according to the observations of GPS-GLONASS receivers for an 11-year period. The main contribution to the variance of variations in the integral moisture content is made by seasonal variations, it is 63 percent. Mesoscale processes yield about 7 percent of the dispersion of moisture content. The network of stations in Russia near Kazan city and the troposphere remote sensing technique made it possible to obtain the seasonal variability in the intensity of mesoscale variations. The daily dynamics of mesoscale inhomogeneity estimation are made, horizontal structure functions of zenith tropospheric delay is calculated. A relationship with the fields of humidity and pressure fields of wind speed is found.

Keywords: water vapor in, mesoscale processes, troposphere, remote sensing, GPS
