It goes without saying that accurate weather forecasts are important for numerous commercial activities such as farming, fishing, transport, energy exploitation and, of course, for generally planning our daily affairs. Our daily forecasts rely on numerical weather prediction, which is a process that generates mathematical models of the current weather to predict what the weather will be like in the future, usually over the next few days. Although weather forecasts have advanced considerably in recent years, Aeolus is set to advance them even further. Global wind profiles delivered in near-real time by Aeolus will help improve numerical weather prediction models, which in turn, will therefore help improve forecasts.
