Online model error correction with neural networks: application to the Integrated Forecasting System

no code implementations6 Mar 2024 Alban Farchi, Marcin Chrust, Marc Bocquet, Massimo Bonavita

In this article, we propose to develop a model error correction for the operational Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts using a neural network.
