The campus is hosting until Friday the celebration of the biannual international meeting Trends, organized by research staff from CIM. Institutions such as NASA, MIT, and the National Center for Atmospheric Research from the USA are participating
From May 6 to 10, the campus of Ourense hosts the celebration of the 12th International Workshop on Long-Term Changes and Trends in the Atmosphere (Trends 2024). It involves 77 specialists from 21 countries and from 51 institutions, participating either in person or virtually, including NASA, the Massachusetts Institute of Technology (MIT), the National Center for Atmospheric Research from the USA, and academies of Sciences from countries such as China, India, and the Czech Republic, as well as Spain.
The 12th International Workshop on Long-Term Changes and Trends in the Atmosphere is organized by the Environmental Physics Laboratory (EphysLab) Group of the Marine Research Center of the University of Vigo with the sponsorship of the International Union of Geodesy and Geophysics, the International Association of Meteorology and Atmospheric Sciences, the Scientific Committee on Solar-Terrestrial Physics of the International Council for Science, and the International Committee on Space Research. Juan Antonio Añel, physicist from the University of Vigo and coordinator of the event, explains that Trends is “the reference forum for people and institutions studying the upper atmosphere,” expressing his satisfaction at hosting its celebration on the campus of Ourense for the first time in Spain. The event, he recalls, brings together every two years specialists working on very diverse topics but related to the upper layers of the atmosphere.
Diversity of Proposals
Throughout the scheduled sessions, the participating scientific community, both in person and online, will address, in the context of climate change, the long-term variations and trends in the middle and upper atmosphere. Specifically, the thematic axes of the event held in Ourense are, always in the context of long-term consideration, the approach to trends in variations in the middle atmosphere; changes and trends in the ionosphere and thermosphere; the dynamic, physical, chemical, solar, and radioactive mechanisms of variations and trends; and changes in the middle and upper atmosphere and their links to satellite navigation and space debris.
The programming kicked off this Monday with a lecture by Jan Laštovička from the Institute of Atmospheric Physics of the Czech Academy of Sciences on the trends scenario of the stratosphere-mesosphere-thermosphere-ionosphere system in light of the new data available in the last two decades. This opened an intense program in which very diverse topics will be addressed, such as advances in the links between climate change and the evolution of mesospheric temperature; the response of thermospheric hydrogen to increased greenhouse gases and changes in solar activity; the evolution of the ionosphere and thermosphere during the Holocene; or the impact of changes in anthropogenic emissions on the appearance of equatorial plasma bubbles.
Priority Research Line
The celebration of Trends 2024 in Ourense culminates two years of work that began with the presentation of the EphysLab candidacy to host this event and its selection by the international scientific committee of the event. For almost two decades, EphysLab has had the atmosphere as one of its priority research lines, developing numerous projects at the national and/or European level with entities also present in this workshop. Among them, since May 2022, an international team led by Juan Antonio Añel has been carrying out a project funded by the International Space Science Institute (ISSI) on the impacts of climate change on the planet’s upper atmosphere, satellite orbiting, and space debris.
