Aeolus is the first satellite mission to directly observe wind profile information on a global scale. After implementing a set of bias corrections, the Aeolus data products went public on 12 May 2020. However, Aeolus wind products over China have thus far not been evaluated extensively by ground-based remote sensing measurements.

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. 2020-05-12 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 main data processing steps for the Aeolus wind and aerosol products is illustrated in Figure 5. Figure 5: Schematic overview of the Aeolus data processing steps up to L2A and L2B. Courtesy: T.

Aeolus wind data

The Aeolus has now an increased loading capacity, accommodation capacity and a helicopter deck. With a top-range crane the vessel can lift more than 1,600 tonnes. This makes the Aeolus suitable for the transport and installation of foundations and wind turbines. It has an advanced jacking system. 2019-09-25 2008-07-05 In 2020, with the COVID-19 pandemic reducing the amount of meteorological data from commercial aircraft and the availability of bias-corrected HLOS winds in real-time, together with very positive forecast scores in the tropics and in the southern hemisphere, Météo-France decided to assimilate Aeolus wind data operationally in their global model on 30 June 2020.

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.

The Aeolus wind data for that path and beyond, from about 6°N to 42°N, are shown below. (Satellite image: NASA) Aeolus horizontal-line-of-sight (HLOS) 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, including the path near Hurricane Dorian shown in the satellite image above. 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.

Aeolus, the wind satellite launched by the European Space Agency (ESA) in August 2018, is ready to share its novel observations with the world. Weather forecasting services and scientific users can now access the data captured by Aeolus in less than three hours of measurements being made from space.

With Aeolus built as a research and demonstrator mission, it has shown its worth as an operational mission with the data being used for everyday weather forecasting, paving the way for a possible future fleet of operational Doppler wind lidar satellites in space.

Aeolus data will provide insight into how the wind influences the exchange of heat and moisture between Earth’s surface and the atmosphere – important aspects for understanding climate change,” said Mr Riishojgaard, who was a member of the Aeolus Mission Advisory Group, an expert body providing independent scientific advice to ESA. Aeolus was launched in August 2018 to test the usefulness of direct wind profile observations from space for numerical weather prediction. It works by measuring the backscatter of laser light from air molecules (‘Rayleigh-clear’ data) and from clouds and aerosols (‘Mie-cloudy’ data).

Aeolus wind data for Hurricane Dorian . The data have been found to be significantly closer to other wind, temperature and humidity observations than when Aeolus data are not assimilated – especially in the southern hemisphere and the tropics which are less covered by conventional observations in the northern hemisphere.

Mie-cloudy winds refer to the winds acquired from Mie backscatter signals induced by aerosols and clouds (Witschas et al., 2020). 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.
