Today, this extraordinary satellite mission has reached new heights: its data will now be distributed publicly to forecasting services and scientific users in less than three hours of space measurement.
Aeolus is one of the ESA Earth Explorer missions to show how new ways of observing Earth can improve our understanding of how the planet works as a system.
Aeolus is one of the most sophisticated instruments ever placed in orbit. This is the first satellite mission to capture Earth’s wind directly from space.
It emits short, strong, and laser ultraviolet light pulses and measures the Doppler shift of the very small amount of light that is scattered back to the instrument by molecules and particles to provide a vertical profile that shows the horizontal velocity of the world’s winds. -The bottom part is 26 km from the atmosphere.
ESA Director for the Earth Observation Program, Josef Ashbacher, said: “Aeolus will never be a simple satellite mission, and actually takes several years to recover before it can be launched.
The wait is definitely worth it, and in 20 months in orbit, he switches from power to power, which will benefit science and society.
Peggy Fisher from ESA said: “A lot of work has been done to improve Aeolus data before today’s release. This satellite technology is completely new, so we have to understand and correct certain distortions in unknown data before launch.
Florence Rabie, CEO of ECMWM, said: “After several months of testing last year, we are confident that we can link the Aeolus wind data with our estimates we have made since January. We are now pleased to see that the distortion has recently been corrected, which is also useful for additional meteorological centers that are preparing to use the data. “”
With Aeolus as a research and demonstration mission, Aeolus has demonstrated its value as an operational mission. This uses data for daily weather forecasts and paves the way for future operational Doppler satellite fleets with lidar winds in space.
