Overall goal

  • The analysis of observations from satellite radar TRMM over Europe (Cyprus)
  • The comparison of rainfall measurements by ground radar and raingauges
  • The comparison of rainfall forecasts by numerical weather prediction models
  • The preparation for the European participation in GPM mission (Global Precipitation Measurement from satellite)
Partners of the VOLTAIRE project are national weather services, universities, a private company, governmental authorities, and research institutes.

Tasks

  • to compare data quality insurance schemes for ground and space radar
  • to use precipitation fields from ground radar and gauge network as ground validation for satellite radar TRMM (over Cyprus)
  • to gain experience for and prepare the European participation in GPM
  • to improve the accuracy of precipitation fields from ground radar in Mediterranean test sites using gauge measurements and adjustment techniques adapted to mountainous regions
  • to compare precipitation fields from numerical weather prediction models with observations from ground and satellite radar
  • to improve accuracy of preciptation fields from ground radar taking into account the intrinsic high variability of precipitation and the error sources in a mountainous region (clutter elimination, correction for visibility, correction for vertical profile of reflectivity, adjustment by gauge measurements)
