DA-TT meeting – May 2023 (Rome)

Overview and meeting objectives
The Data Assimilation-Task Team (DA-TT) fosters the development and evaluation of data assimilation systems relevant to OceanPredict to support the coordination of the fundamental and challenging issues in the ocean forecasting process, of which data assimilation is a significant part.
The meeting aims to bring together experts in the field of ocean and coupled data assimilation (DA) to discuss the latest progress and challenges in the field, and to share experiences in the development of ocean/coupled data assimilation from the underlying algorithms to the details of implementation in operational forecasting systems. Overarching topics of discussion include:
- How to improve integration of ocean DA developments in operational forecasts and demonstrate the impacts on ocean and coupled forecasts.
- How to contribute to the UN Decade for Ocean Science. Examples include the role of DA in digital twins, ocean best practices, and the evaluation and design of ocean observing systems. Should the DA-TT organise its own contribution to the UN Decade?
- How to link better with the WMO community and other external groups. Examples include the input of ocean observation requirements to WMO, links to the DAOS working group, and links to the ISDA.
Meeting format
The workshop will take place over 3 days.
The meeting will be an in-person event with presentations recorded and made available afterwards.
The meeting will consist of oral presentations selected through the abstract submission process and organised by the themes listed below.
Poster presentations will also be included with dedicated poster sessions.
The overarching discussion points are listed on the meeting objectives tab.
Date, venue and location
- 9-11 May 2023
- Task Team meeting
- CNR, Rome, Italy
The workshop will be held at the CNR headquarters in central Rome (piazzale Aldo Moro, see more information at https://www.cnr.it/en/reach-headquarters ; location visible at https://www.google.com/maps/place/Piazzale+Aldo+Moro,+00185+Roma+RM). CNR headquarters are close to the main University campus (“La Sapienza”), not far from the main railway station “Roma Termini” and the student neighborhood San Lorenzo.
There are plenty of options for accommodation nearby. Lunches are expected to be offered by the local organizers, while dinner is at everyone’s expense.
Expected attendees
The meeting is primarily intended for participation by DA-TT members, the wider OceanPredict community and other experts in ocean and coupled DA, machine learning, ocean forecasting and reanalysis. Junior scientists and graduate students are also encouraged to attend.
