This page is the gateway to access and download the free and open Aeolus science data products

Aeolus scientific as well as preliminary wind products are openly available in Near Real Time (NRT). As from May 26, 2021, Aeolus data is produced with the latest processor baseline 12.

Important Note: Please take note that the Aeolus reference Orbit will shift in the second half of June 2021 from ANX 4.5 to ANX 2.0, in order to facilitate ground based Aeoluscampaign activities.
The drift from one to the other orbit is expected to start in the night of June 17/18 2021 and will take between a minimum of a few days and a maximum of a couple weeks.
All predictions of ground tracks during the drifting period can be subject to sudden changes in the solar activity and therefore change quickly.
The focus in the Aeolus orbit prediction files is on keeping the first 2 weeks of their 4 weeks prediction period valid as far as possible.

Additionally, the Aeolus Level-2C data product is openly accessible, which provides the ECMWF model wind vectors at the geolocations of assimilated Aeolus L2B winds.
