Based on data from ESA’s Aeolus wind mission, the image shows how the polar vortex in the lower stratosphere changed between December 1, 2020, and February 1, 2021. The first few plots at the beginning of December show the vortex in a comparatively normal state, but in mid-December patches of blue wind appear, and the wind is going westwards relative to normal conditions.

First wind data from ESA’s Aeolus satellite. 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.

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. A series of research experiments in which Aeolus wind data were assimilated has been performed at ECMWF over the last 12 months. After several refinements in how the data were assimilated, the results were so promising that Aeolus was assimilated operationally from 9 January 2020. Impact on forecasts.

Aeolus wind data

The satellite data is provided by KSAT in Near Real-Time from the two unique polar ground stations, Arctic Svalbard and Troll Antarctica. Image Courtesy: ESA. 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 Aeolus, or, in full, Atmospheric Dynamics Mission Aeolus (ADM-Aeolus), is an Earth observation satellite operated by the European Space Agency (ESA). It was built by Airbus Defence and Space and launched on 22 August 2018. ADM-Aeolus is the first satellite with equipment capable of performing global wind-component-profile observation and will provide much-needed information to improve weather Considering the accuracy and precision of the A2D wind data, which were determined from comparison with a highly accurate coherent wind lidar as well as with the European Centre for Medium-Range Weather Forecasts (ECMWF) model winds, the systematic and random errors of the Aeolus LOS* Rayleigh winds are 1.7 and 2.5 m s −1 respectively.

Tests carried out at ECMWF show that when Aeolus data are combined with short-range forecast information in a process called data assimilation, the short-range forecasts used are improved. Aeolus horizontal-line-of-sight wind observations measured in the direction of the laser beam and projected onto the horizontal plane, on 1 September 2019 between about 6°N and 42°N. Assess the potential improvements on short-term regional dust forecasts attributed to the assimilation of Aeolus wind profiles; Investigate the modifications of dust emission and transport mechanisms by contrasting numerical simulations initialized with and without Aeolus observations; Rayleigh-clear winds refer to the wind observations in aerosol-free atmosphere.

The quality of the Aeolus wind data is indicated by validity flags (0 is invalid, and 1 is valid) and estimated errors (theoretical). Aeolus: Wind satellite weathers technical storm One of the reasons Esa, its member states and the data-user community was so patient with Aeolus's development was that wind measurements in general Se hela listan på knmi.nl The tasks of the Aeolus DISC include the instrument and platform monitoring, calibration, characterization, retrieval algorithm refinement, processor evolution, quality monitoring, product validation, and impact assessment for NWP.The achievements of the Aeolus DISC for the NRT data quality and the current status of Aeolus wind measurements will be described and summarized. 2008-07-05 · July 2008 Data Processing for ADM-Aeolus – LWG Wintergreen & JCSDA Slide 1 The Wind Lidar Mission ADM-Aeolus Data Processing David Tan Research Department ECMWF Acknowledgements: ESA (Mission Science & Aeolus project team) Aeolus Mission Advisory Group Level-1B/2A/2B Development Teams Image copyright PA Image caption Aeolus data should mean there are fewer surprises in the forecasts. A British-assembled satellite has been launched into space to make the first truly global maps of wind behaviour. The Aeolus spacecraft will get its data by firing a powerful laser down into the atmosphere to trace the movement of air particles.

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.

The European Centre for Medium-Range Weather Forecasts (ECMWF), after months of careful testing, has started to operationally assimilate data from the European Space Agency's Aeolus satellite in its daily weather forecasts. Aeolus measurements have been considered ready for operational use as early as 14 months after the satellite launch, which is unusual for data collected from a new type of Aeolus is the first satellite mission to directly observe wind profile information on a global scale.

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.
