Minimize What is Aeolus?

The Earth Explorer Atmospheric Dynamics Mission Aeolus will provide global observations of wind profiles from space to improve the quality of weather forecasts, and to advance our understanding of atmospheric dynamics and climate processes.

Although there are several ways of measuring wind from a satellite, Aeolus will utilise the active Doppler Wind Lidars (DWL) method. This is the only method that has the potential to provide the required data globally, from direct wind observations. In addition, a DWL will provide information on cloud top heights, vertical distribution of cloud, aerosol properties, and wind variability. This information is a useful by-product of the DWL method.

An improved model of the Earth's climate and atmosphere will lead to progress in numerical weather prediction (NWP), especially concerning long-term forecasting. It is widely recognised that a new global atmospheric observing system, such as Aeolus, will have a great effect upon operational weather forecasting. The provision of detailed wind profiles will also benefit scientists involved with climate research, allowing for greater accuracy in the numerical modelling of tropical regions in particular.

Wind satellite vacuum packed

02 November 2017

With liftoff on the horizon, ESA's Aeolus satellite is going through its last round of tests to make sure that this complex mission will work in orbit. Over the next month, it is sitting in a large chamber that has had all the air sucked out to simulate the vacuum of space.

New portal for EVDC

22 August 2017

The ESA Atmospheric Validation Data Center (EVDC) has been migrated to a new portal with upgraded functionalities and new tools. The portal offers access to both Cal/Val data and Satellite products for specific missions. The user community is invited to exploit these new features and to contact the EVDC team for any further information.
