  • This dataset provides the processed ECC ozonesonde radiosoundings performed for 5 consecutive nights at the Maïdo Observatory (21.08°S, 55.38°E) on Réunion Island during the period 20-25 January 2022 following the eruption of the Hunga Tonga volcano on 15 January. Réunion Island is in the Southwest Indian Ocean and holds one of the very few atmospheric observatories in the subtropical Southern Hemisphere.

  • FLEXPART (“FLEXible PARTicle dispersion model”) is a Lagrangian transport and dispersion model suitable for the simulation of a large range of atmospheric transport processes. Applications range from the dispersion of radionuclides or air pollutants, over the establishment of flow climatologies, to the analysis of Earth’s water cycle. FLEXPART also produces output suitable for inverse determination of emission sources, e.g., of greenhouse gases or volcanic ash. Paramètre principal: . Contexte de la mesure: STRAP.
