Observations are a key component of DA. Space agencies invest billions of pounds in providing wide-ranging, high-resolution observations of the Earth to improve weather forecasting. These observations...

by Sukun Cheng, March 2026 To understand historical ocean changes, researchers produce reanalyses that reconstruct past states by combining numerical models with historical observations. Over the last...

Explainable AI, data assimilation and their connection in Earth sciences. Approaches used in DA may help to understand and trust AI models.

Gaussian anamorphosis for log-normal distribution in data assimilation

A recent community paper, Parameter Estimation in Land Surface Models: Challenges and Opportunities with Data Assimilation and Machine Learning, addresses a deceptively simple question with far-reachi...

By Alison Fowler At the end of September, I joined approximately 100 scientists from operational centres and academia, each contributing to progress in data assimilation. Together in Melbourne for the...

Our recent NERC/NCEO/DARC Training course on data assimilation and its interface with machine learning took place from 9-13 June 2025 at the University of Reading and online. It was wonderful...Read M...

The biggest tech firms are using AI to forecast the weather but is that better than existing models?

by Jemima M. Tabeart, TU Eindhoven When designing data assimilation algorithms, we want to exploit access to lots of parallel computational resource, while ensuring that we can obtain our results...Re...

This blog highlights new methods for improving data assimilation in coupled atmosphere-ocean systems. Traditional approaches struggle with the differing scales of the ocean and atmosphere. A new techn...

by Amos Lawless, April 2025 Why is the ocean relevant for weather forecasts? The weather we experience each day is influenced not just by what is happening throughout the atmosphere,...Read More >

by Ross Bannister, April 2025 The method of least squares (or MLS, Barlow, 1993) is at the very centre of variational data assimilation (or “Var”, Schlatter, 2000). Var is one...Read More >
