GLONET is a neural network-based ocean forecasting system developed by [Mercator Ocean International](https://www.mercator-ocean.eu/), which architecture is described in the [scientific paper](#citation), outputting in seconds a 10-days daily forecasts of the temperature, sea surface height, salinity and currents at 1/4 degree resolution (1/12 degree effective resolution) over 21 depth levels.
Visit [GLONET website](https://glonet.lab.dive.edito.eu) for more information.

<figcaption>Overview of GLONET's architecture containing different modules, particularly time-block designed to learn feature maps encapsulating initial conditions along with forcings. A spatial module architectured to learn multi-scale dynamics, and finally an encoder-decoder to fuse multi-scale circulations into a unified latent space.</figcaption>
