[Webinar Series] Volcanic eruptions and aerosols – what did we learn from the Hunga-Tonga?<\/strong><\/h2>\n<\/div>On January 15, 2022, the undersea volcano at Hunga Tonga-Hunga Ha\u2019apai erupted. At the time, signals evaluated by ECMWF showed that material from the eruption rose higher than 20 km. According to recent research, it rose in fact to 58 km, and the event gained worldwide attention.[1<\/a>]<\/p>\n![\"-\"](\"https:\/\/reuniwatt.com\/en\/wp-content\/uploads\/sites\/3\/2022\/03\/hunga-tonga-13-02-2022-001.jpg\" "\\"\\"")

In this webinar, our experts will share how and why atmosperic scientists observe the mix of aerosols in our atmosphere and which effects resulted from the Hunga-Tonga eruption.
\nWe are proud to have Dr. Vincent-Henri Peuch<\/strong>, Director Copernicus Atmosphere Monitoring Service<\/span> at ECMWF, the European Centre for Medium-Range Weather Forecasts, on board as moderator. He will introduce the audience to the mix of aerosols in our atmosphere. Two experts, Dr. Alexandre Baron and Dr. Damien Ceus, will provide you with accessible scientific information from their perspectives with a focus on the effects of the Hunga-Tonga eruption. Dr. Alexandre Baron<\/strong> will introduce how you to how aerosols are observed and measured, including insights into the Ma\u00efdo atmospheric station in Reunion Island, how a LiDAR works, and give details on the transport of the aerosols from the site of the eruption and the remarkable features of the plume! Finally, Dr. Damien Ceus<\/strong> will put a focus on the effect of these aerosols on human activities. After introducing the function of Clear Sky Models to calculate the impact of aerosols, he will take a closer look at the impact of aerosols from Hunga-Tonga on renewable energy production worldwide.<\/p>\nWe are kindly inviting scientists, professionals and interested amateurs, who want to learn more about the work of some of the leading observatories and the impact of aerosols from volcano eruptions on our everyday life and electricity production.<\/p>\n<\/div>

He has been involved since 2003 in the design, development and implementation of Copernicus, the flagship Earth Observation programme of the European Union. A native of France, he obtained his PhD from Ecole Normale Sup\u00e9rieure de Lyon in 1996. He worked as a scientist for M\u00e9t\u00e9o-France for 15 years before joining ECMWF in 2011 to lead the precursor European R&D activities that eventually led to CAMS. He is an internationally respected scientist working on numerical modelling and data assimilation of air quality and atmospheric composition with over 100 peer-reviewed publications. He serves in several national and international scientific committees, including for the World Meteorological Organization and the World Health Organization.<\/span><\/p>\nDr. Alexandre Baron<\/span> <\/strong>is a postdoctoral researcher at the Laboratory of the atmosphere and cyclones (LACy, La R\u00e9union University), specialized in aerosols processes and remote-sensing measurements by lidar. After studying fundamental physics at the University of Paris-Saclay, he completed a PhD at the Laboratory of Climate and Environmental Science (LSCE), funded by the CEA. Now beneficiating of a CNES postdoctoral fellowship, he is pursuing studies on aerosols transported across the Indian Ocean using instruments based in Reunion Island (OPAR Observatory), satellite observations, and atmospheric modelling products.<\/span><\/p>\nDr. Damien Ceus<\/span> <\/strong>obtained a PhD in Instrumentation for Astrophysics (Facult\u00e9 des Sciences de Limoges – Laboratoire Xlim). He worked as a field engineer at Leosphere for 4 years and then as a metrology and support engineer at HGH Infrared Systems for 3 years. He joined Reuniwatt’s Toulouse office in the beginning of 2021 to take responsibility of Sky Imagers in the visible and the infrared wavelength domain. Damien manages the instrumentation team to ensure that each camera follows a series of tests and calibrations. He also participates in the product definition and development of new functionalities. He ensures that Reuniwatt maintains a high quality standard of production and that all our customers’ individual technical requests are answered.<\/p>\n<\/div><\/div><\/div>![\"-\"](\"https:\/\/reuniwatt.com\/en\/wp-content\/uploads\/sites\/3\/2022\/03\/VHPeuch_square_400.jpg\" "\\"VHPeuch_square_400\\"")
