Downscaling of oceans fields by fusion of heterogeneous observations using Deep Learning Algorithms

Satellite images of heterogeneous data (SST, SSH, salinity, biological activity) are taken at different scales. This subject focuses on using the highest resolution images (SST) to enhance the images of coarse resolution (SSH). Another objective is to estimate the ocean current fields. We want to use Deep Learning algorithms on these super resolution key questions.
