Masterclass | The Role of Data Assimilation in Forecasting and Reanalysis
LOCATION
Data assimilation provides Earth system models a route to incorporate information from the extensive network of observation instruments. In this way, data assimilation is crucial to the skill of modern-day numerical weather prediction and is also essential for reconstructing historical weather systems in the form of reanalyses.
The theory of data assimilation is based on applying Bayes' theorem to the Earth system. To efficiently solve Bayes' theorem, various data assimilation algorithms have been proposed, each making different assumptions about the error characteristics of the model and observations.
In this lecture, I will provide a brief introduction to the main data assimilation algorithms. We will discuss their advantages and limitations within the context of the challenges in the advancing field of numerical weather prediction and reanalysis. These challenges include the increasing resolution of models, the growing number of components of the Earth system being modelled, and the greater variety of instruments being used.
Speaker
Dr Alison Fowler
Alison is a National Centre for Earth Observation Research Fellow based at the University of Reading. She has over 15 years of experience in the development of data assimilation theory and its application to a variety of environmental challenges. In close collaboration with the Met Office, her recent work includes the development of metrics to help establish new observation networks and the quantification of observation uncertainty to improve the assimilation of existing observations.
Before joining the University of Reading to study for a PhD in Meteorology, Alison obtained a BSc in Mathematics and an MRes in Physics of the Earth and Atmosphere from the University of Leeds.

Masterclass Series Abstract
Continuing its online Meteorological Masterclasses in partnership with the University of Reading, the Society is pleased to announce a new series for Autumn 2024.
During this series, three leading experts from the University of Reading will discuss the latest scientific advances for understanding and predicting weather, climate, and its impacts.
These masterclasses are intended to provide support for professionals working in Meteorology and Climate Science, and its operational applications who wish to remain up to date on recent scientific developments in the field.
