In our concept paper from May 2022 (cf. related identifiers), we addressed the continuously increasing demand for using High-Performance-Computing (HPC) infrastructure in the Earth System Sciences (ESS), and the challenges arising from this for the National Research Data Infrastructure (NFDI). From a description of typical use cases, we derived challenges in FAIR (Findable, Accessible, Interoperable, Reusable) Research Data Management (RDM) and computational workflow/data-flow management, as a motivation for driving developments of the NFDI Consortium Earth System Sciences (NFDI4Earth) on the HPC-centric side. We issued recommendations that relate to these possible developments, and scheduled a recommendation status review after 12-24 months. This addendum discusses current and future topics with increasing significance for RDM in HPC in the ESS – together with a set of new recommendations related to these topics. It then reviews the fulfilment status of our previous recommendations and lays out necessary adjustments. This addendum extends the original concept paper of 2022: https://doi.org/10.5281/zenodo.6565405
