We evaluated the potential of satellite-based remote sensing to detect the effects of high temperatures on grapevines in a South Australian vineyard over the 2016\u20132017 and 2017\u20132018 seasons. The study involved: (i) comparing the normalized difference vegetation index (NDVI) from medium- and high-resolution satellite images; (ii) determining correlations between environmental conditions and vegetation indices (Vis); and (iii) identifying VIs that best indicate heatwave effects. Pearson\u2019s correlation and Bland\u2013Altman testing showed a significant agreement between the NDVI of high- and medium-resolution imagery (R = 0.74, estimated difference \u22120.093). The band and the VI most sensitive to changes in environmental conditions were 705 nm and enhanced vegetation index (EVI), both of which correlated with relative humidity (R = 0.65 and R = 0.62, respectively). Conversely, SWIR (short wave infrared, 1610 nm) exhibited a negative correlation with growing degree days (R = \u22120.64). The analysis of heat stress showed that green and red edge bands\u2014the chlorophyll absorption ratio index (CARI) and transformed chlorophyll absorption ratio index (TCARI)\u2014were negatively correlated with thermal environmental parameters such as air and soil temperature and growing degree days (GDDs). The red and red edge bands\u2014the soil-adjusted vegetation index (SAVI) and CARI2\u2014were correlated with relative humidity. To the best of our knowledge, this is the first study demonstrating the effectiveness of using medium-resolution imagery for the detection of heat stress on grapevines in irrigated vineyards.<\/jats:p>","DOI":"10.3390\/rs11232869","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T04:58:39Z","timestamp":1575349119000},"page":"2869","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Assessing the Feasibility of Using Sentinel-2 Imagery to Quantify the Impact of Heatwaves on Irrigated Vineyards"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8354-7324","authenticated-orcid":false,"given":"Alessia","family":"Cogato","sequence":"first","affiliation":[{"name":"Department of Land, Environmental, Agriculture and Forestry, University of Padova, 35020 Legnaro (PD), Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1916-2758","authenticated-orcid":false,"given":"Vinay","family":"Pagay","sequence":"additional","affiliation":[{"name":"School of Agriculture, Food and Wine, The University of Adelaide, PMB 1, Glen Osmond, SA 5064, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3283-5665","authenticated-orcid":false,"given":"Francesco","family":"Marinello","sequence":"additional","affiliation":[{"name":"Department of Land, Environmental, Agriculture and Forestry, University of Padova, 35020 Legnaro (PD), Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1693-7709","authenticated-orcid":false,"given":"Franco","family":"Meggio","sequence":"additional","affiliation":[{"name":"Department of Agronomy, Food, Natural Resources, Animals and the Environment, University of Padova, 35020 Legnaro (PD), Italy"}]},{"given":"Peter","family":"Grace","sequence":"additional","affiliation":[{"name":"Institute for Future Environments, Queensland University of Technology, Brisbane, QLD 4000, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5651-5834","authenticated-orcid":false,"given":"Massimiliano","family":"De Antoni Migliorati","sequence":"additional","affiliation":[{"name":"Institute for Future Environments, Queensland University of Technology, Brisbane, QLD 4000, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18711","DOI":"10.3390\/ijms140918711","article-title":"Berry phenolics of grapevine under challenging environments","volume":"14","author":"Teixeira","year":"2013","journal-title":"Int.
