Version 2.2 (Changelog)
VirES for Swarm is a highly interactive data manipulation and retrieval interface for the ESA Swarm constellation mission products. It includes tools for studying various geomagnetic models by comparing them to the Swarm satellite measurements at given space weather and ionospheric conditions.
Here is a demonstration of the VirES for Swarm tools and main features.
Slides with detailed information on service usage can be found here.
Magnetic and plasmatic Swarm product data can be visualized on the platform plotted over the globe and shown in a scatterplot. The scatterplot allows for dual y-axes with independent zoom and panning features. The time slider and various controls offer the possibility to make selections and set criteria for data filtering and visualization which immediately take effect on the display.
The subset of Swarm data selected by the user in this way can be downloaded in different encoding formats. The data downloaded can be combined to fit various use cases.
VirES enables visual and numerical comparison with geomagnetic models, analysis with respect to various ancillary data and generation of publication-ready plots and diagrammes in an intuitive and powerful yet customizable interface.
The following products are taken from all three Swarm Satellites:
The following models of the Earth's magnetic field and its time variation are pre-loaded:
The following Spherical Harmonic Models of the Core Field are available:
The following Spherical Harmonic Models of the Lithosphereic Field are available:
The following Spherical Harmonic Models of the Magnetospheric Field are available:
The following Spherical Harmonic Models of the Daily Geomagnetic Variation are available:
Users can also work with Custom Models and upload Spherical Harmonic Expansion coefficients (SHC file format)
The global context of space weather is provided in form of:
The data accessible on VirES consists of the newest versions available and any new data will appear within 4 hours of generation.
