On the 12th of May, the OVL tool has been presented by Dr. Fabrice Collard during the Living PLanet Symposium. We have selected several examples where the benefit of the OVL web client is fully exploited.
Here you have an example of different observations during CARTHE experiment where 1100 drifters were launched. Surface velocity Profilers are shown over High Resolution SST from VIIRS and Ocean Color from Sentinel 2.
This picture is a nice example of the synergy of remote sensing observations. Are represented:
Aviso along track SSH from CRYOSAT 2, SARAL-ALTIKA and JASON 2 POSEIDON
Streamlines derived from Aviso Geostrophic Current
South Africa Regional SST from ODYSSEA product
Trajectories of Surface Velocity Profilers
By over laying the different products we can see dynamical structures visible in the SAR image are in agreement with the one visible in the SST image. However, the lack of resolution of altimetry data does not unable to capture the dog head structure and thus the corresponding streamlines are not following well frontal structures from SAR and SST.
