Abstract text Researchers making use of Swarm data products face several challenges. These range from discovering, accessing and comprehending an appropriate dataset for their research question, to forwards evaluation of various geomagnetic field models, to combining their analysis with external data sources. To help researchers embarking on this journey and to facilitate more open collaboration, Swarm DISC is defining and building new *tools* and *services* that build upon the existing data retrieval and visualisation service, *VirES for Swarm*.

Given Swarm's large data product portfolio and diverse user community, there is no "one size fits all" solution to provide an analysis platform. A sustainable, modular framework of smaller tools is needed, leveraging the wider open source ecosystems as much as possible. To answer this, we are developing Python packages that can be used by researchers to write their own reproducible research code using well-tested algorithms, Jupyter notebooks that guide them in this process, and web dashboards that can give rapid insights. These are supported by the *Virtual Research Environment (VRE)* that provides the free pre-configured computational environment (JupyterHub) where such code can be executed.

We provide the Python package, *viresclient*, that provides the connection between the VirES API and the Python environment, delivering customised data on-demand with a portable code snippet. On top of this, we are building Python tools that can apply specific analyses (such as cross-correlation of measurements between spacecraft for studies of field-aligned currents and ionospheric structures), which can be used by researchers in an open-ended way. In-depth documentation and tutorials are critical to make these tools accessible and useful, while an open source and community-involved focus should bring them longevity.

With this presentation, we present the current status of Swarm DISC activities in relation to tools and services, and guidance on how to navigate and provide feedback on these. Please also see our poster "VirES & VRE for (not only) Swarm" (Martin Pačes & Ashley Smith)
