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. 

The Aeolus mission was launched on 22 August 2018.

Improving new Aeolus wind data for forecasts

12 November 2019

Tests carried out show that new wind profile observations from ESA's Aeolus satellite significantly improve weather forecasts – particularly in the southern hemisphere and the tropics.
