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.

Assessing the accuracy of data being returned by completely new technology in space is a challenging task. But this is exactly what engineers and scientists have been dedicating their time to over the last months so that measurements of the world's winds being gathered by Aeolus can be fed confidently into weather forecast models.

The first in-orbit Aeolus Cal/Val and Science Workshop will be held at ESA-ESRIN (Frascati, Italy) from 26 to 29 March 2019. The workshop will focus on the mission status, first data quality and Cal/Val results, the planning of the NWP impact assessment, and on the scientific exploitation of Aeolus data including current and possible future products.
If you would like to attend the workshop, act soon, as pre-registration is mandatory and the deadline is 25 February 2019.
