Although many studies indicated a linear relationship between precipitable water values derived from GPS measurements and those derived from radiosonde or water vapor radiometer measurements, no such evidence has been reported for the combination of synthetic aperture radar (SAR) interferometry and radiosonde measurements. Therefore, this study compares SAR atmospheric delay with the delay calculated using data from a radiosonde launched within the SAR scene extent. As might be expected, the result shows a clear linear relationship between delays calculated by the two methods. The result also reveals that large spatial variations in the atmospheric delay can occur within a small area. Moreover, we discuss various meteorological processes that generate the spatial variation of the delay.
