Aeolus-2
Aeolus-2
| ESA / EUMETSAT | Approved | Dec 2031 | Dec 2041 | Aelous-2 will provide global wind profile measurements for Numerical Weather Prediction using backscattered UV laser light to measure Doppler shifts. It will also provide atmospheric aerosol profiles.
In addition, Radio Occcultaion profiles will be obtained to determine atmospheric temperature and humidity profiles using Galileo, GPS and Beidou.
