Description
The Trieste Solar Radio System (TSRS), consisting of two multi-channel solar radio polarimeters, monitored decimetric and metric solar coronal emissions from 1969 to 2010. It recorded flux and polarisation at multiple frequencies with high temporal resolution, resulting in a dataset that spans over four solar cycles and contains thousands of solar radio bursts (Types II, III, IV), background coronal emission and long-term solar radio flux variability. This unique resource provides key diagnostics of solar activity, facilitating connections between radio signatures, energetic particle events and heliospheric disturbances. It is equally valuable for compiling comprehensive event catalogues and for reconstructing long-term solar variability within the context of space climate.
The TSRS Heritage Archive (TSRS-HA) project aims to preserve and modernise this legacy. The digitised collection from 1999 to 2010 has been re-ingested into a searchable database, offering fast and flexible access to the complete time series. Over the past year, the archive has evolved into a FAIR-aware infrastructure, supported by a modular and portable framework that enables user-friendly services, such as Jupyter notebooks for reproducible analyses and cookbook-style data exploration. To maximise interoperability, TSRS-HA is being aligned with key community standards: the IVOA Table Access Protocol (TAP) for rich metadata and complex queries; ObsTAP and EPN-TAP for both atomic datasets and extended historical series; and the Heliophysics Application Programming Interface (HAPI) for dedicated time series discovery and access. These choices ensure seamless integration with the heliophysics and space weather ecosystems, broadening the archive’s reach and scientific impact.
Alongside the digitised collection, efforts are underway to recover and digitise historical material stored on analogue media — ranging from magnetic tapes to ceramic supports and photographic plates — covering observations back to 1968. Their future integration into TSRS-HA will extend the temporal baseline and enrich catalogues of past solar radio events, further enhancing the scientific value of the archive.
This contribution highlights the scientific significance of TSRS data, presents the current status of TSRS-HA, and outlines its roadmap as a long-term open resource for heliophysics, space weather, and space climate research.
