... The development of the NVAP data set and the advancement of validation processes during the initial phase of GVaP led the GEWEX Science Steering Group to conclude that the success of the pilot period, coupled with recognition of the potential importance of upper tropospheric and lower stratospheric water vapor for GEWEX, had set the stage for GVaP to make major contributions to GEWEX. An international planning workshop for GVaP was held in November 1996 in Geneva, Switzerland, at which representatives from WCRP, the National Oceanic and Atmospheric Administration (NOAA)

... . The main phase of GVaP is being initiated with a series of workshops and research meetings to advance knowledge of water vapor data set calibration/validation issues, including algorithm development and data intercomparison.

... It will also lead to the development of an improved suite of water vapor products that include separate satelliteonly, ground-only, and blended data sets. Such a hierarchical approach will allow independent comparison amongst the various data sources and merged products.
