DARC/NCEO Data Assimilation Training course, Univ. of Reading, 2023
Data assimilation is one of the core activities needed to deliver weather forecasts, and to help understand the environment. This course will provide an introduction to data assimilation methods used in numerical weather prediction, including some of the latest developments. All methods will be derived from a common framework to allow a full overview of their assumptions and applicability. Furthermore, participants will get the opportunity to apply data assimilation methods to small numerical models, in order to obtain hands-on experience with the different methods.
- Tuesday 9th – Friday 12th May 2023.
- University of Reading, UK (Covid restrictions permitting; an on-line course will be offered if in-person lectures are not possible).
- A map of the campus is available here.
- Who is it for?
- This course is suitable for postgraduate students, post-doctoral researchers, and weather service employees who would like an introduction to, and a deeper understanding of, data assimilation.
- How will the course be delivered?
- The course will be a combination of lectures and computer practicals.

Course timetable and lecture/practical material
The course will be held mainly in the Brian Hoskins Building (aka Meteorology Building, BH/Met, building 58), but also in the Agriculture Building (Ag, building 59). These are on the main Whiteknights campus of the University of Reading (campus map). Registration and most lectures will be in room BH/Met 1L61.
Handouts will not be provided by the lecturers, but lectures can be downloaded via the on-line timetable below when they become available.
