The publication of large datasets poses significant challenges for research data management, particularly regarding storage, access, citability, and adherence to FAIR principles. We present our experience publishing a 25 TB dataset from the Infrared Atmospheric Sounding Interferometer (IASI) covering October 2014 to June 2019 (MUSICA IASI v3.2.1) using a hybrid approach. A representative one-day subset was deposited in the institutional repository RADAR4KIT with a DOI, while the complete dataset is archived at the Large Scale Data Facility (LSDF) provided by the Scientific Computing Center (SCC) at KIT and accessed via a THREDDS Data Server (TDS) hosted by IMKASF at KIT. We describe the workflow, metadata harmonisation, persistent linking strategy, and lessons learned from this publication process.
