8th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction and Earth System Prediction

The 8th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction (NWP) and Earth System Prediction (ESP) will be organized by WMO and will be hosted by the Swedish Meteorological and Hydrological Institute (SMHI) in Sweden, at the SMHI main office in Norrköping, on 27-30 May 2024. Participation from all the major numerical weather prediction (NWP) centers and communities active in the field of impact studies about the observing systems is anticipated. The Workshop will be held in a hybrid format (in-person and remote participation will be enabled), and will be conducted in English.

WMO’s Impact Workshop series is an important quadrennial venue for providing science evidence on the impacts of surface and space-based observing systems, on short to medium and longer-range forecasting including climate monitoring. Conclusions from the Workshop provide guidance on how to optimize the use of the current global observing system as well as help guide its future evolution.

This 8th Workshop will continue to focus on assessing the impacts of various observing systems in all Earth system domains on NWP, but will extend the scope to also encompass the impact assessment of the various observing systems, to other Earth system applications. This is done in order to achieve a comprehensive understanding of the value of the observations and to support the strategic goals of WMO.

Experts who have results of impact assessment of various observing systems, especially those responding to the science questions, are invited to submit a short abstract. Contributions to the Workshop may fall within general topics that will frame the Workshop sessions (to be determined at a later stage), or they may simply address one or several of the specific studies and science questions. Note that to increase the chances of being responsive to this call, abstracts should clearly articulate what type of impact assessment(s) will be presented.

Abstract submission deadline is December 15, 2023.
