This presentation will give insights into the GPS and ERA-Interim IWV datasets provided to WG3 for the assessment of homogenization algorithms: - Processing characteristics of IGS repro1 (and their limitations) - Screening of the GPS ZTD data - Conversion of GPS ZTD to IWV - Computation of ERA-Interim IWV data at the location of GPS stations - Statistical analysis of GPS minus ERA-Interim IWV differences - Screening and validation and of the IWV differences (removal of sites with large representativeness differences) The dataset is limited to 120 global sites with data available for the 1995-2010 period. The IWV data and differences are provided at daily and monthly time resolutions.
