WMO Workshop on Aircraft-based Water Vapour Measurement for Aviation Application
The World Meteorological Organization (WMO) organized a workshop on Aircraft-based Water Vapour Measurement for Aviation Application from 7 to 8 December 2023 in Offenbach, Germany. The workshop was hosted by the Deutscher Wetterdienst (DWD), at their headquarters in Offenbach, Germany.
The workshop covered the current status of aircraft-based water vapour measurements, their benefits to weather forecasting especially for aviation and also their use for further aviation applications particularly focusing on contrail detection, monitoring, prediction and avoidance.
The workshop summary can be downloaded here.
