Note on Submission Service

Limitations on External Submissions - June 2026

The GHGA Data Portal was launched in summmer 2024. Since then, substantial improvements have been made, including support for data uploads from external users. Current development focuses on further enhancing metadata handling and streamlining the submission workflow to provide a scalable, user-friendly experience suitable for national operation.

At present, submissions from external users outside the GHGA Consortium still require some manual processing and therefore cannot yet be fully supported at scale. If you are interested in submitting data, please refer to our FAQ and the corresponding user story.
