We would like to let you know that the 8th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction (NWP) and Earth System Prediction (ESP), will take place on 27-30 May 2024. Organized by The World Meteorological Organization (WMO), the workshop will be hosted by the Swedish Meteorological and Hydrological Institute (SMHI), at their headquarters in Norrköping, Sweden.

Workshop sessions will be structured around science questions related to ocean observations and beyond, several of which may be of particular interest to the marine biogeochemistry observing community (e.g. around the role of eularian and lagrangian observations in assessing and forecasting changing biogeochemical cycles). Please see more details on the proposed science questions below.

The online abstract submission will open in June 2023 and will remain open until the end of 2023. More details will follow in due course.

Science questions relevant to ocean observations:

Ocean-Based in-situ observing system

S1.12: What is the impact of eulerian (e.g. moorings like the tropical mooring arrays, tidal gauges) and lagrangian (e.g. Argos, gliders, drifters) ocean observing platforms on NWP, and the forecast of the blue (physics, wave), green (biogeochemistry, ecosystem) and white (polar) ocean?

S1.13: What is the impact of Argo (including deep Argo) on the assessment of climate change on the ocean (including the deep ocean)?
- For instance, what is the impact of BGC Argo on the assessment of ocean deoxygenation, acidification, and air-sea fluxes of CO² and O²? What is the impact of Core Argo on the assessment and prediction of the ocean heat budget, water mass formation, heat waves, etc.?

S1.14: What are the impacts of assimilating non-traditional marine-based observing systems on marine forecasting?
- For example, radiometric/hyperspectral ARGO, Underwater Vision Profilers (UVP), underway systems (e.g. Ship Of Opportunity Programme (SOOP)), sensors of marine animals (e.g. Animal Borne Ocean Sensors (AniBOS))

Impact on Oceanography

S3.12: What are the impacts of atmosphere, ocean (including surface and subsurface), and sea-ice observations on oceanography applications?

S3.13: What ocean observations are directly needed in support of emergency response and sustainable development in the most vulnerable areas to sea level rise and flooding, such as low-lying islands and coasts?

S3.14: What is the suitable temporal and spatial resolution for the observation of glacier and ice sheets to support glacier and ice sheet modeling and predictions (and links to sea level rise)?

S3.15: What Ocean observations would be the most impactful for better wave and storm surge predictions? What observations are required to optimize the performance of these ocean wave models especially for high impact (storm) events?
