摘要：Improved knowledge of atmospheric water vapor and its temporal and spatial variability is of great scientific interest for climate research and weather prediction, but also geodetic positioning applications using GPS and radar interferometry will benefit. In this article a comparison is made of MERIS and GPS based integrated water vapor data, retrieved at the same day over Western Europe. For both signals a variance-covariance analysis is made, that will be applied in producing a time series of combined water vapor maps by means of the geostatistical Cokriging approach
