DWD Offenbach, Germany, 9-11 July 2018


The purpose of the workshop is to:

  • Identify the form of a new IPWG/GEWEX Precipitation assessment chapter on extreme precipitation including identifying the chapter lead and other contributors
  • Finalise a best practice guidance document for the WCRP GC Extremes on data use for assessing precipitation extremes
  • Better integrate the remote sensing community in the extremes chapter of the IPCC Sixth Assessment Report (AR6)

The workshop will have only a few introductory presentations on the first morning but the majority of time at the workshop will be taken up with open discussions and breakout sessions to address the above bullet points and associated gaps.
