Recent studies suggest\u00a0this saturation may be an appearance resulting from uncertainties in solar wind data, leading to the illusion\u00a0of a weaker geomagnetic response during strong solar wind conditions. If true, we might be underestimating\u00a0the geomagnetic response to extreme space weather events, potentially resulting in unexpectedly severe\u00a0geomagnetic effects beyond current predictions. As we approach solar maximum, the likelihood of super-geomagnetic storms rises, making it timely and necessary to bring together scientists with expertise in different\u00a0aspects of the solar wind-magnetosphere-ionosphere system to address critical science questions:\u00a0<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif\">1) What are the main contributors to the observed non-linearity of the geomagnetic response?<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif\">2) How does geomagnetic activity respond to different extreme solar wind driving parameters?<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif\">Our team will investigate these questions by performing a correlation analysis of an extensive database\u00a0of solar wind measurements and geomagnetic indices. We will be the first to assess whether the observed\u00a0non-linearity in geomagnetic response is real or an artifact of statistical effects resulting from uncertainties by\u00a0quantifying them. Crucially, we can only answer question-2 and understand the true geomagnetic response to\u00a0extreme solar wind driving by first addressing the uncertainties and answering question-1. We expect multiple\u00a0extreme geomagnetic storms during the project, enabling timely, accurate analysis of these extreme events,\u00a0directly benefiting the space science community and also space weather-preparedness.<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif\">We are a team of 11 scientists from across the world with expertise in different aspects of space physics hoping to address the above science questions from multiple different vantage points.\u00a0<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif\">Team leads:<\/span><\/p>\n<p><span style=\"font-family: helvetica, arial, sans-serif\">Maria-Theresia Walach (UK) &amp; Nithin Sivadas (US)<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Geomagnetic indices, widely used to measure solar wind-driven geomagnetic activity, appear to saturate under extreme solar wind conditions, but the cause remains an open question.
