RESEARCH POSTER PRESENTATION DESIGN © 2015 www.PosterPresentations.com Studied areas in coastal zone for SST and the preparation of the TRISHNA mission: The Mediterranean sea along the coast from the Bay of Banyuls/Mer up to Marseille : → Submesoscale processes (~ 1-10km) (link with the SWOT mission) up to the scale of mixing/dissipation (100 m-1km): → Diurnal cycle, mixing after a wind event, river discharge and plumes, groundwater discharges especially around the in situ observations for the SST: moorings (LF/HF) examples: in the Bay of Banyuls/Mer (this poster), lagoons • Côte Sud-Nord avec un canyon → difference (Airborne SST/Landsat SST – HF in situ SST) = - 0.5°C (POEM Station) And = -1°C (SOLA Station) → Difference (satellite SST at 9:20am – Airborne SST at 10am) = - 0.1°C Laboratoire d’Etudes en Géophysique et Océanographie Spatiales – Toulouse – F - France I.

Bourrin (CEFREM, Perpignan, F) Sea surface temperature (SST) in coastal ocean with different data: application for the TRISHNA mission Scientific context Scientific context Study thermal infrared signals (TIR) for the determination of sea surface temperature (SST) in the coastal environment (Mediterranean Sea) by different data (airborne, satellite, in situ data, model outputs) and methods, complementary in their spatio-temporal resolutions and coverage in order to prepare the TRISHNA mission (CNES/ISRO - 2025) (algorithm, products and expectations in coastal environment) Main scientific question Main scientific question Studied Area: Mediterranean Sea Studied Area: Mediterranean Sea SST data and models used with different spatial resolution SST data and models used with different spatial resolution Conclusion & perspectives Conclusion & perspectives References References Results Results Berk, A. et al.
