摘要：
We compared two datasets of the total content of atmospheric water vapor received near St. Petersburg in 2009–2012 from ground-based Fourier transform spectroscopy measurements at the Peterhof station and from radio sounding at Voyeykovo station. Despite a good correlation of daily measurements in Peterhof and Voyeykovo, the standard mismatch is significant, 20% or more, for most subsets taken for the comparison. The high mismatch is mainly due to the natural spatial variability of the total content of water vapor, accounting for the 50-km distance between Peterhof and Voyeykovo. This variability needs to be considered when validating the satellite measurements of water vapor content by ground-based measurements. © 2015, Pleiades Publishing, Ltd.
