WORLD METEOROLOGICAL ORGANIZATION WORLD WEATHER RESEARCH PROGRAMME WWRP 2010 – 5 5th WMO SYMPOSIUM ON DATA ASSIMILATION Melbourne, Australia, 5 - 9 October 2009 WMO/TD-No.1549 Foreword Improving the combination of observations and dynamical models by data assimilation systems has underpinned many advances in our understanding of the natural environment, and forecasting ability. These improvements, coupled with the development of ever more powerful computers and more sophisticated communication systems such as the internet and the World Wide Web have also heightened expectations. As a result, society is looking for further significant benefits from applications of meteorology, oceanography and hydrology. It is therefore essential that this community continue to meet and plan the research and development of data assimilation: its fundamental theory and its application to meteorology, oceanography, hydrology and related fields. The use of data assimilation within areas such as modelling chemical species, coupled systems and the land surface raises many new issues. These questions come on top of those associated with continued efforts to meet the expectations from more established atmospheric and oceanic applications. Since the WMO accepted the challenge to oversee the development of Data Assimilation there has been tremendous developments in the relevant areas of science, both research and operational. This series of meetings from the first in Clermont-Ferrand (1990) followed by Tokyo (1995), Quebec City (1999), Prague (2005) and now Melbourne, have been an important part of showcasing these developments and reporting on fruitful directions for research to meet the increasing demands. The presentations at this meeting show that despite the success of existing systems, new developments are still needed to bridge the gap between current and desired levels of performance. The number of presentations on new techniques, novel combinations of established techniques and enhanced use of more elaborate observing systems highlights the dynamism within data assimilation theory and application.
