Radiosounding data are used to estimate the atmospheric water vapor content, starting from the meteorological parameters (Temperature, Pressure and Relative Humidity) measured by the sonde at different altitudes. Data taken at Mexico City are used as example. The number density of H2O is estimated at the altitudes where the radiosonde takes data. It is found that, for December, January and February, the scale height of water vapor content takes the highest values of the year. The Precipitable Water Vapor (PWV) is estimated by integrating the density of water vapor molecules from various lower limits. Histograms of the PWV values obtained for the lower limits of integration have been also made. For summer time the histograms of the PWV have a maximum that takes place at 35 mm for 2.0 km and shifts to lower values as the lower limit of integration increases. For winter time, the histograms for low lower limits of integration do not have a prominent maximum but are considerably spread. However, for the PWV integrated from the highest low limits of integration the Histograms have a well defined maximum and the shape of the distributions is rather sharp. In winter time at Mexico City, which is a mid-altitude site, the PWV takes values as low as those observed at 5-6 km altitude.
