Geomagnetic Conditions Expert Service Centre

The mission of the Geomagnetic Conditions ESC (G-ESC) is to provide and develop the functionalities, capabilities and expertise in the domain of geomagnetism that are needed within the ESA SSA SWE Network to achieve as a collaborative enterprise its mission of demonstrating and assessing the influences of Space Weather and informing and supporting end-users through the provision of accurate, reliable and timely products and (pre) operational services, tailored to their requirements.
The G-ESC thus provides, implements and supports the geomagnetic products and capabilities of the ESA SSA SWE network for monitoring, interpreting, and forecasting variations of the geomagnetic field on various timescales, relying on in situ ground-based, as well as space-borne measurements and related derived quantities and models.

This page provides access to the latest data, products and analysis tools from the SSA SWE Geomagnetic Conditions Expert Service Centre.
