WebECMWF is a world leader in data assimilation research and development. The quality of our forecasts depends on how well we use information received in real-time from the global observing system, which consists of numerous satellite instruments, weather stations, ships, buoys, and other components. The purpose of data assimilation is to ... WebFeb 28, 2008 · Data assimilation schemes are confronted with the presence of model errors arising from the imperfect description of atmospheric dynamics. These errors are usually modelled on the basis of simple assumptions such as bias, white noise, and first‐order Markov process.
