This study presents an analysis of the responses of dryland vegetation to the worst extreme drought over the past two decades in Australia, using multi-source spaceborne SIF derived from the Global Ozone Monitoring Experiment-2 (GOME-2) and TROPOspheric Monitoring Instrument (TROPOMI). Vegetation functioning was substantially constrained by this extreme event, especially in the interior of Australia, in which there was hardly seasonal growth detected by neither satellite-based observations nor tower-based flux measurements. At a 16-day interval, both SIF and enhanced vegetation index (EVI) can timely capture the reduction at the onset of drought over dryland ecosystems. The results demonstrate that satellite-observed SIF has the potential for characterizing and monitoring the spatiotemporal dynamics of drought over water-limited ecosystems, despite coarse spatial resolution coupled with high-retrieval noise as compared with EVI. Furthermore, our study highlights that SIF retrieved from TROPOMI featuring substantially enhanced spatiotemporal resolution has the promising capability for accurately tracking the drought-induced variation of heterogeneous dryland vegetation.<\/jats:p>","DOI":"10.3390\/rs14071581","type":"journal-article","created":{"date-parts":[[2022,3,27]],"date-time":"2022-03-27T21:29:36Z","timestamp":1648416576000},"page":"1581","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Assessing the Impact of Extreme Droughts on Dryland Vegetation by Multi-Satellite Solar-Induced Chlorophyll Fluorescence"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6724-9597","authenticated-orcid":false,"given":"Song","family":"Leng","sequence":"first","affiliation":[{"name":"Fujian Provincial Key Laboratory of Remote Sensing of Soil Erosion, College of Environment & Safety Engineering, Fuzhou University, Fuzhou 350116, China"},{"name":"School of Life Sciences, University of Technology Sydney, Ultimo, NSW 2007, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2809-2376","authenticated-orcid":false,"given":"Alfredo","family":"Huete","sequence":"additional","affiliation":[{"name":"School of Life Sciences, University of Technology Sydney, Ultimo, NSW 2007, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jamie","family":"Cleverly","sequence":"additional","affiliation":[{"name":"College of Science and Engineering, James Cook University, Cairns, QLD 4878, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6429-1917","authenticated-orcid":false,"given":"Sicong","family":"Gao","sequence":"additional","affiliation":[{"name":"Land and Water, Commonwealth Scientific and Industrial Research Organization, Adelaide, SA 5064, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Life Sciences, University of Technology Sydney, Ultimo, NSW 2007, Australia"},{"name":"State Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau, Northwest A&F University, Xianyang 712100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianyong","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Atmospheric Physics, Nanjing University of Information Science & Technology, Nanjing 210044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junyu","family":"Qi","sequence":"additional","affiliation":[{"name":"Earth System Science Interdisciplinary Center, University of Maryland, College Park, MD 20740, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1089-1869","authenticated-orcid":false,"given":"Rongrong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Remote Sensing of Soil Erosion, College of Environment & Safety Engineering, Fuzhou University, Fuzhou 350116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8460-6821","authenticated-orcid":false,"given":"Qianfeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Fujian Provincial Key Laboratory of Remote Sensing of Soil Erosion, College of Environment & Safety Engineering, Fuzhou University, Fuzhou 350116, China"},{"name":"Key Lab of Spatial Data Mining & Information Sharing, Ministry of Education of China, Fuzhou 350116, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"558","DOI":"10.1029\/2018EF001087","article-title":"The Sensitivity of Satellite Solar-Induced Chlorophyll Fluorescence to Meteorological Drought","volume":"7","author":"Jiao","year":"2019","journal-title":"Earth\u2019s Future"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1016\/j.plaphy.2021.04.029","article-title":"Effects of Irrigation on Ecophysiology, Sugar Content Andthiol Precursors (3-S-Cysteinylhexan-1-Ol and 3-S-Glutathionylhexan-1-Ol) on Vitis Vinifera Cv.
