Data download

The EUI consortium is committed to a maximally open data policy meaning that all data products, low latency data products, the calibration software and science user documentation will be made available as soon as possible and as broadly as possible. This implies specifically that the EUI consortium will not exercise the right foreseen in the Solar Orbiter Management Plan (Solar Orbiter 2012) to retain the data private during 3 months after the receipt of the original telemetry for the purpose of calibration and verification. Instead, the EUI data products will be distributed as soon as is technically possible with the best known calibration at the time of production.

The full EUI data archive will be reprocessed on a regular basis to apply the continuously improving instrument understanding and calibration optimisation. Each such reprocessing will be distributed as a new release of the data. Each release contains Level 1  (L1, uncalibrated images), Level 2 (L2, calibrated images) and Level 3 (L3, JP2000 visualisation product) data. General science users are encouraged to use the L2 images from the latest release. L1 images are only relevant for data users who wish to study the calibration process. L3 images are intented to be viewed through jHelioviewer. Typically only L2 data will be upgraded in a new release. L0 data will never change by definition. L1 data will only be upgraded if the metadata content is changing. L3 data will only upgrade if the changes imply a visually perceptible change. Previous versions of the data, corresponding to old releases, will continue to be available for reproducibility of past research.

The currently recommended data set is avalaible at http://sidc.be/EUI/data/releases/202107_release_3.0/L2/
Data users are asked to read the release notes and cite it's DOI landing page.

The history of previous EUI data releases is available at
https://wwwbis.sidc.be/EUI/data/releases/ 

All EUI science data will also become available eventually from the Solar Orbiter Archive (SOAR). EUI science data will be further propagated through Virtual Observatories.
