    Ten years of Swarm data help reveal processes in Earth’s core

    The tenth birthday of ESA’s three-satellite Swarm constellation has been a game changer for research into Earth’s magnetic field and core dynamics, as set out by an ESA-funded project.

    SWESMAG

    The project SWESMAG relies on magnetic field data from Swarm to investigate Space Weather (SWE) effects related to Geomagnetic Induced Currents (GICs), driven mainly by rapid variations of the ionospheric Polar Electrojet (PEJ) currents and quantified (loosely) by the variation of the horizontal ground magnetic field component dH/dt.

    Swarm’s orbital dance: counter-rotating and closer, for the benefit of science

    Since variations in Earth’s magnetic field directly reflect the flow of fluid in the outermost core, new information from Swarm will further our understanding of the physics and dynamics of Earth's stormy heart—and the satellites are recently flying in a counter-rotating phase and closer in their separation, to enable scientists to discover new elements.

    Swarm Field-Aligned Current Dual (FAC_AC) data unavailable from 4 May 2022

    Due to the recent orbit raise manoeuvres which changed the orbital configuration of Swarm Alpha and Charlie, no Field-Aligned Current Dual (FAC_TMS_2F) data are being produced since 4 May 2022.

    Swarm DISC pre-study 5.1 

    Understanding the complex dynamics of neutral winds in the upper atmosphere is crucial for understanding thermosphere-ionosphere interactions. However, the limited availability of measurements and data coverage has hindered the comprehensive characterization of these winds.

    Ship trails in the Bay of Biscay observed using PROBA-V imagery

    Ship trails have been perceived as convincing evidence of aerosol-cloud interaction. Ship emissions have been proven to contribute by about 1.9% and 2.9% to the increase in the global total and fine-mode aerosol optical thickness (AOT) respectively over a five year period (Peters et al. 20212).
