This study attempts to quantify the changes in the stratospheric water vapour and its relationship to temperature and ozone observed from space-based Microwave Limb Sounder (MLS) observations during the submarine volcano eruption Hunga Tonga-Hunga Ha\u2019apai that occurred on 15 January 2022. The most notable aspect of this eruption is the plumes, which are water vapour columns that reached higher altitudes (1 hPa (47.6 km)) than earlier eruptions. We discovered that the eruption injected a record amount of water vapour (6\u20138 ppmv) directly into the stratosphere from 38\u201310 hPa vertically, which is present even after one year. The majority of water vapour is confined to the Southern Hemisphere (SH) tropics, i.e., 30\u00b0S to 5\u00b0N, and gradually descends to the SH polar latitudes over time. The WV from the lower stratosphere reaches mesospheric altitudes during January 2023. We quantify the impact of increased water vapour on temperature and ozone as well. Temperatures begin to fall during the month of March in the regions where there is an increase in water vapour. A ~5 K cooling occurs in July and August as a result of the thermal adjustment to the extra water vapour IR cooling. Our analysis shows a decrease in ozone caused by an increase in water vapour. Significant variability is observed in all three parameters at 26 km compared to other levels. Further, we noticed that after one year of eruption, the water vapour, Temperature and Ozone did not reach the background values. It is possible that this unusual eruption produced a different atmospheric reaction than other significant volcanic eruptions that have been well investigated.<\/jats:p>","DOI":"10.3390\/rs15143602","type":"journal-article","created":{"date-parts":[[2023,7,19]],"date-time":"2023-07-19T21:21:46Z","timestamp":1689801706000},"page":"3602","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Impact of Hunga Tonga-Hunga Ha\u2019apai Volcanic Eruption on Stratospheric Water Vapour, Temperature, and Ozone"],"prefix":"10.3390","volume":"15","author":[{"given":"Ghouse","family":"Basha","sequence":"first","affiliation":[{"name":"National Atmospheric Research Laboratory, Department of Space, Gadanki 517112, India"}]},{"given":"Madineni Venkat","family":"Ratnam","sequence":"additional","affiliation":[{"name":"National Atmospheric Research Laboratory, Department of Space, Gadanki 517112, India"}]},{"given":"Alladi Hemanth","family":"Kumar","sequence":"additional","affiliation":[{"name":"National Atmospheric Research Laboratory, Department of Space, Gadanki 517112, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5929-8951","authenticated-orcid":false,"given":"Jonathan H.","family":"Jiang","sequence":"additional","affiliation":[{"name":"Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA 91109, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1313-8864","authenticated-orcid":false,"given":"Saginela Ravindra","family":"Babu","sequence":"additional","affiliation":[{"name":"Department of Atmospheric Sciences, National Central University, Taoyuan 32001, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0076-5452","authenticated-orcid":false,"given":"Pangaluru","family":"Kishore","sequence":"additional","affiliation":[{"name":"Regato, Rancho Santa Margarita, CA 92688, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11697","DOI":"10.5194\/acp-20-11697-2020","article-title":"Impact of the eruption of Mt Pinatubo on the chemical composition of the stratosphere","volume":"20","author":"Kilian","year":"2020","journal-title":"Atmos.
