Abstract
The water vapor is an atmospheric component which is not evenly distributed. If we consider the total water vapor content in a vertical column, i.e. the precipitable water, W it may change from 0.5 g/cm2 for high latitudes to about 6 g/cm2 for equatorial zones. All that makes it impossible to know its distribution with only radiosondes data, because their validity is restricted to a few km2. In order to correctly characterize the water vapor content over the sea around the Canary Islands, we have used brightness temperatures of TOVS sensors onboard NOAA satellites. We have compared the total water vapor content obtained with radiosondes data, launched by Instituto Nacional de Meteorologia at Santa Cruz de Tenerife, with the nearest free-clouds data from satellite for a set of fifty days of 1994. The statistics generated with the comparison are shown and the validity of the humidity fields determined with only TOVS data are discussed.
