The VirES service as a platform for accessing and analysing geomagnetic data

VirES is an ESA service which was been developed to support the goals of the Swarm mission, providing a number of mechanisms for accessing and working with Swarm products. It has since been extended to cover other LEO datasets under the Swarm umbrella: calibrated platform magnetometer data from Cryosat-2, GRACE, GRACE-FO, GOCE, as well as INTERMAGNET ground observatory data, with plans for more. We provide a graphical web interface (currently only supporting Swarm data) [1], API-based access via both the OGC standards and the HAPI specification [2], a Python client [3], and a Jupyter-powered cloud environment (so-called Virtual Research Environment - VRE) and associated notebook collection [4]. Through these connected approaches, we provide a variety of pathways for interaction with the data and models (see also: the Swarm data handbook [5]).

Swarm activities are shifting to toolboxes and on-demand processing (to interactively deliver higher-level products), more open-source software, and more connection with other datasets and data providers. We provide some of these Python tools preinstalled in the VRE alongside other thematic libraries, and are developing SwarmPAL [6] in collaboration with the Swarm community.

These works contain contributions from EOX IT Services and many people across ESA, Swarm DISC, and the wider community.
