Abstract
The importance of data in meteorological data assimilation can be quantified in the context of re-analyses performed at Numerical Weather Prediction centres. The increasing quality and quantity of satellite data is seen to play a major role in the improvement of forecast performance, particularly in the Southern hemisphere. Further optimisation of the use of observations is possible through proper evaluation of the data impact, optimisation of the amount of data to be assimilated and of their error characteristics, and a relevant selection of data based on information content concepts. A more interactive forecasting system including an adaptive observation component is a new challenge to bring additional improvement in the forecasting of high-impact weather.
