DiffDA: a Diffusion model for weather-scale Data Assimilation

no code implementations11 Jan 2024 Langwen Huang, Lukas Gianinazzi, Yuejiang Yu, Peter D. Dueben, Torsten Hoefler

The experiments also show that the initial conditions assimilated from sparse observations (less than 0. 77% of gridded data) and 48-hour forecast can be used for forecast models with a loss of lead time of at most 24 hours compared to initial conditions from state-of-the-art data assimilation in ERA5.

Denoising Weather Forecasting

Compressing multidimensional weather and climate data into neural networks

1 code implementation22 Oct 2022 Langwen Huang, Torsten Hoefler

We propose a new method of compressing this multidimensional weather and climate data: a coordinate-based neural network is trained to overfit the data, and the resulting parameters are taken as a compact representation of the original grid-based data.

ENS-10: A Dataset For Post-Processing Ensemble Weather Forecasts

1 code implementation29 Jun 2022 Saleh Ashkboos, Langwen Huang, Nikoli Dryden, Tal Ben-Nun, Peter Dueben, Lukas Gianinazzi, Luca Kummer, Torsten Hoefler

We propose the ENS-10 prediction correction task for improving the forecast quality at a 48-hour lead time through ensemble post-processing.
