A number of tools are available for visualising, processing and analysing Aeolus data.
Data visualisation tools
VirES for Aeolus
VirES for Aeolus is a highly interactive data manipulation and retrieval interface for ESA's Aeolus mission products. It includes tools for studying various atmospheric parameters, in space and time, measured by the Aeolus satellite.
CODA and HARP
The ESA Common Data Access (CODA) and HARP tools have been developed for reading atmospheric data from the ESA Envisat satellite, and have been extended to read Aeolus data in the common Earth Explorer File Format.
Satellite and orbit visualisation tools
ESOV - the Earth Observation Swath and Orbit Visualisation tool - provides the means to visualise the instrument swaths of all ESA Earth Observation Satellites and assist in understanding where and when satellite measurements are made and ground contact is possible.
EVDC Orbit Prediction Tool
The EVDC Orbit Prediction Tool generates and visualises satellite's overpasses, including Aeolus. Temporal overpasses can be calculated for any time period - either past or future - for any location.
SAMI (Satellite Mission Editor & Player) is a freely available software application for visualisation of high-resolution 3D and 2D scenarios of ESA Earth Observation satellites.
Command line executables
The Earth Observation CFI Software is a collection of precompiled C libraries for timing, coordinate conversions, orbit propagation, satellite pointing calculations, and target visibility calculations.
The following Aeolus products are available to all users:
- Level 1B: Preliminary HLOS (Horizontal Line of Sight) wind observations and useful signals for Rayleigh and Mie receivers. Standard atmospheric correction, receiver response and initial bias corrections applied.
- Level 2A: Scientific aerosol/cloud profile product. Geo-located consolidated backscatter and extinction profiles backscatter-to-extinction and lidar ratio per observation, scene classification, and scene heterogeneity index and attenuated backscatter on measurement level.
An experimental feature mask product is also available, but flagged invalid and should only be used for testing. More information on Level 2A products usage can be found in the Level 2A user guide
- Level 2B: Scientific wind product for users. Geo-located consolidated HLOS wind observation with actual atmospheric correction and further bias corrections applied.
- Level 2C: Aeolus assisted wind fields resulting from NWP (Numerical Weather Prediction) assimilation processing. Data co-located time and space with Aeolus wind observations.

The ESA framework for Aeolus data quality assurance is the Aeolus DISC (Data, Innovation and Science Cluster), including processor evolution, quality monitoring and a central role in calibration, validation and NWP impact assessment. It consists of expert centres and teams located in Germany, UK, France, Italy and the Netherlands and is led by the German Aerospace Center (DLR).
Aeolus Quality Control Reports on L1B/Instrument, L2A and L2B products are currently available to Aeolus Cal/Val teams and will become publicly available after public data release.
Data Unavailability Reports contain information on all periods of planned and unplanned unavailability of Aeolus ALADIN data.
Major processor releases are scheduled twice per year. The current Aeolus Near Real Time (NRT) data products are available in the latest processor baseline 13, activated on 6 December 2021. A summary of the main improvements brought by the baseline 13 processors are available in the Main processor improvements for Baseline 13 document.
Data from 26 May to 6 December 2021 are available in baseline B12.
Additionally, a fully-homogeneous dataset is available in baseline 11, covering the time period from 10 October 2020 to 26 May 2021 (from NRT production) in combination with the reprocessed dataset covering the period 28 June 2019 to 10 October 2020 (published on the 11 October 2021). This establishes for the first-time a seamless low bias data availability for the whole FM-B time-series (laser B of Aeolus, in operation since June 2019). A summary of the new reprocessed dataset is available in the Aeolus-Summary-Reprocessing-2 document .
Note: The Level-2B products from the above-mentioned reprocessed period are available now both in (nominal) EEF and BUFR format.
Detailed descriptions of all released Baselines are available on the processor releases page.
Announcement of Opportunity
An announcement of opportunity is open for calibration and validation (cal/val) teams to apply for Aeolus data. The aim of the call is to invite new groups to participate in Aeolus cal/val activities, and as such the teams will have early access to Aeolus data products before their public release.
