The Space Weather Research Group at the University of Alcala (SWE-UAH) has strong expertise in the Sun-to Earth chain. More than 40 peer review papers related to the Sun-Earth interaction guarantee the experience acquired in the framework of both national and international projects. Although improving scientific knowledge on the solar terrestrial is the main goal for SWE, the research group has proven experience in the development of space weather products, leading the Spanish Space Weather Service (http://www.senmes.es) and providing products to the European Space Agency (ESA) through the ESA SSA SWE Network (http://swe.ssa.esa.int/).
