The ESA A-TSCV project is organizing a workshop on 13 June 2023 on the project outcomes and future opportunities derived from the project work and plans.
This workshop aims at sharing experience in assimilating ocean surface velocity data. Today, HF radar data are assimilated in operational systems. Future space missions should observe total surface currents. Lesson learnt from past experience and design experiments to assess the impact of future observations will be discussed as well as assimilation methods well suited for those observations. Current status and challenges for efficiently assimilating surface ocean current observations from diverse observing platforms will be identified, in research and operational context. Observation gaps and requirements for operational systems will be discussed.
General topics to be addressed in this workshop include:
- Assimilation of direct velocity observations from HF radar, drifting platforms, ADCP, future space missions, SAR measurements, …
- Assimilation methods for surface currents, including Lagrangian and Eulerian approaches,
- Surface current estimation via data assimilation from coastal to global scale.
- Observation operators for assimilation of total surface current

Bus and train connections
Tickets bought for a journey are valid on metro and bus.
The nearest Metro station to MOi is Rangueil (Ligne B). It is possible to walk from Rangueil to MOi (marked with a red start below) from that station but it takes 30+ minutes. Alternatively, you can take a bus from Rangueil (its quite frequent)
- Line 23, stop Jardins de la Ligne (see image one the right, with the stop near MOi)
- Line 80, stop Latécoère (a stop before Jardins de la Ligne)
Other bus connections:
- Linéo 8, stop Piste des Géants (departures directly from the city center)
From Matabiau SNCF station Toulouse to Montaudran SNCF station, but the number of trains is very limited.
It is advisable to book into a hotel in Toulouse centre and to use pubic transport to get to MOi. For hotel bookings please refer to hotel booking websites or your travel agent. Examples of hotels in the centre are listed below.
