But, there's been a gap in the wind measurements available to forecasters for decades. Existing satellites could measure the wind speed over the sea, and above thick clouds, but nowhere else! Now, data from the European Space Agency's Aeolus satellite is plugging the gap, and has been incorporated into weather forecasting models for the first time.

ECMWF has begun to process wind profile data from the ground-breaking Aeolus satellite launched on 22 August 2018. First comparisons with ECMWF model data are very encouraging. ECMWF now expects to start assimilating Aeolus data operationally in 2019. ECMWF is contracted by the European Space Agency (ESA) to produce Aeolus wind products suitable for use in numerical weather

About Aeolus ESA's Earth Explorer, Aeolus, was launched into space on 22 August 2018. This new satellite type provides novel global observations of wind profiles from the surface up to 30 km altitude. Although there are several ways of measuring wind from a satellite, Aeolus utilises the active Doppler Wind Lidars (DWL) method. ESA’s Aeolus mission scientist, Anne Grete Straume, explained, “These first wind data shown in the plot made by ECMWF are from one orbit. In the profile we can see large-scale easterly and westerly winds between Earth’s surface and the lower stratosphere, including jet streams. Additionally, the Aeolus Level-2C data product is now openly accessible, which provides the ECMWF model wind vectors at the geolocations of assimilated Aeolus L2B winds. The previous baseline 09 has been reprocessed in baseline 10, which provides users access to a fully homogeneous dataset from 20 April to 8 October 2020.

Reading Time: 2 minutes Barely a fortnight after Aeolus satellite blasted off from ESA’s spaceport in French Guiana, the world’s first wind monitoring satellite has surpassed all expectations by delivering the first set of wind data. This is a phenomenal achievement that has come earlier than anyone’s anticipation. Florence Rabier, Director General of the European Centre for Medium-Range

In the profile we can see large-scale easterly and westerly winds between Earth’s surface and the lower stratosphere, including jet streams. A series of research experiments in which Aeolus wind data were assimilated has been performed at ECMWF over the last 12 months.

These data are from three quarters of one orbit around Earth. The image shows large-scale easterly and westerly winds between Earth’s surface and the lower stratosphere, including jet streams. Based on data from ESA’s Aeolus wind mission, the image shows how the polar vortex in the lower stratosphere changed between 1 December 2020 and 1 February 2021.

Aeolus is the first satellite capable of observing what the winds are doing on Earth, from the surface of the planet and into the stratosphere 30 km high. Recently, Aeolus has taken one leap further: on 12 May 2020, its wind data, that was previously accessible only to expert user groups involved in validation activities, became publically available. Aeolus carries a single payload, ALADIN, which is a direct-detection wind lidar operating at an ultraviolet wavelength of 354.8 nm. ALADIN emits short laser pulses (≈40 to 70 mJ, 50.5 Hz) down to the atmosphere where a few of the photons are backscattered on air molecules, aerosols and hydrometeors. ECMWF is contracted by ESA to develop, in collaboration with KNMI and other partners of the Aeolus DISC the Aeolus Level 2B/C (L2B/C) processing software i.e. the wind retrieval.
