In particular, we investigate the application of the Kriging geostatistical technique to obtain regularly spaced IPWV values. The horizontal spatial structure r water vapor retrieved by SSM/I is explored by computing-variograms that provide a measure of dissimilarity between pairs IPWV values for the region of interest. Because the water vapor density decreases with height, the GPS station elevation - accounted for in the interpolation procedure. In this respect, the potential of the Kriging with external drift relative to the linary Kriging is evaluated by applying a test based on the validation approach.The case studies are presented and qualitatively compared to the corresponding Meteosat infrared images. A quantitative comparison with an independent source of information, such as IPWV computed from radiosonde observations and from European Centre for Medium-Range Weather Forecasts only, is also performed.
