IWV intercomparisons

During the COST action ES1206 "Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate" (GNSS4SWEC), a literature overview of comparisons of Integrated Water Vapour (IWV) retrievals by GNSS with other techniques was undertaken. The most important findings that came out of this literature overview can be consulted in the Final Report of this COST action.  It is also this section in the Final Report that should be used for referencing and acknowledgement when using this literature overview. The presentation of this literature overview, given at a workshop of this COST action can be found here.

Below, you find a table (with references at the bottom) of the IWV inter-technique studies involving GNSS, that (mostly) appeared in the peer-reviewed literature. For each study, chronologically ordered, you find the spatial extent, the time period covered, the different techniques or Numerical Weather Prediction (NWP) models, and possibly remarks. At the bottom (or in the tab "references"), the full reference of the study is provided. The table will be updated as much as possible, you can therefore contact me.
