Weekly Comparison of GPS PWV Results  Long Term Comparison Tables


These plots display comparisons of the near-real-time PWV estimates with estimates obtained with post-processed CODE or IGS orbits. PWV from radiosonde data (RAOBS) are also plotted for comparison with the GPS solutions when available. A time span of one week is shown for each station. The plots are updated daily when new RAOBS data become available.
     Only the near-real-time PWV estimates (the last 1-hour segment of each hourly 24-hour solution) are compared to the post-processed solution and to RAOBS, because these are the values that an operational forecasting system would assimilate. Data gaps indicate problems with data availability in near real time. Often data, that were not available in near-real-time become available with the daily files provided by NOAA.
