The ACTRIS CiGas Data flagging & Data submission workshop, held on 15 January 2026, brought together more than 50 participants for a highly engaging and productive exchange.
The event focused on recent updates in the data submission process, providing participants with a clear overview of the main steps required for data submission within ACTRIS CiGas.

A central part of the workshop addressed the data flagging of NOx and VOC data, introducing new flags and explaining how and what to flag to ensure high-quality and harmonized datasets. Special attention was given to the guidelines on local event flagging, supported by practical examples to illustrate typical use cases and best practices.
