Presented at the GHRSST XXIII international science team meeting, 27 June-1 July 2022, online and in-person (Barcelona). #GHRSST23 Short abstract Sea surface temperature (SST) at the ocean-atmosphere interface represents a key variable for understanding, monitoring and predicting heat, momentum and gas fluxes as well as ocean dynamics over a wide range of spatio-temporal scales. In coastal areas, the intense exchanges between the ocean/atmosphere/continent generate a very high variability of the surface temperature both in time and space, which makes the data of the future TRISHNA mission suitable for many applications. We are interested in the study of sub-mesoscale structures (100 m -1 km) in the coastal environment, having an impact on productivity and ocean-atmosphere fluxes. We study thermal infrared (TIR) signals for the determination of SST in the coastal environment using different data and methods that are complementary in terms of their spatio-temporal resolution and coverage in order to prepare theTRISHNA mission : airborne measurements, satellite measurements and in situ measurements. SAFIRE airborne flights equipped with infrared cameras took place in the Gulf of Lion off Banyuls/Mer in the Mediterranean Sea in September 2019. We then compared the SST deduced from airborne data, LANDSAT images and in situ data. The results show a good agreement between the 3 types of data (temperature difference |
