Abstract(in English) | SSTs are essential information for ocean-related industries but are hard to measure. Although multi-spectral imaging sensors on meteorological satellites are used for measuring SSTs over a wide area, they cannot measure sea temperature in regions covered by clouds, so most of the temperature data will be partially occluded. In meteorology, data assimilation with physics-based simulation is used for interpolating occluded SSTs, and can generate physically-correct SSTs that match observations by satellites, but it requires huge computational cost. We propose a low-cost learning-based method using pre-computed data-assimilation SSTs. Our restoration model employs adversarial physical model loss that evaluates physical correctness of generated SST images, and restores SST images in real time. |
