Data Assimilation Training in collaboration with the ECMWF 2018, Univ. of Reading, 7-10th March 2018
Introduction
This 4-day intensive course on advanced data-assimilation methods will be given by members of the Data Assimilation Research Centre and the National Centre for Earth Observation. The course will provide an introduction to all data-assimilation methods used in numerical weather prediction, including the latest developments. All methods will be derived from a common framework to provide an overview of the assumptions and hence applicability of the different methods. The course also provides hands-on computer practicals to see the methods in action and gain a better understanding of their working. For those unfamiliar with data assimilation, or those who are keen to develop a deeper understanding of data assimilation methods, this course is a solid preparation for the main Data Assimilation ECMWF course held on 12-16 March 2018.
Overview
An overview of the subjects covered is given below, including some supplementary material covering the basic mathematics. A map of Reading, Whiteknights campus can be found here.
