AB  - This paper shows the validation of integrated water vapor (IWV) measurements 
      retrieved from the Ozone Monitoring Instrument (OMI), using as reference nine 
      ground-based GPS stations in the Iberian Peninsula. The study period covers from 
      2007 to 2009. The influence of two factors, - solar zenith angle (SZA) and IWV -, 
      on OMI-GPS differences was studied in detail, as well as the seasonal dependence. 
      The pseudomedian of the relative differences is -1 +/- 1% and the inter-quartile 
      range (IQR) is 41%. Linear regressions calculated over each station show an 
      acceptable agreement (R(2) up to 0.77). The OMI-GPS differences display a clear 
      dependence on IWV values. Hence, OMI substantially overestimates the lower IWV 
      data recorded by GPS ( approximately  40%), while underestimates the higher IWV reference 
      values ( approximately  20%). In connection to this IWV dependence, the relative differences 
      also show an evident SZA dependence when the whole range of IWV values are 
      analyzed (OMI overestimates for high SZA values while underestimates for low 
      values). Finally, the seasonal variation of the OMI-GPS differences is also 
      associated with the strong IWV dependence found in this validation exercise.
