This study explored how the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) can give new insight into irrigation allocation and plant health. Leveraging the global coverage and 70-m spatial resolution of the Evaporative Stress Index (ESI) from ECOSTRESS, we processed over 200 overpasses and examined patterns over 3 growing seasons across the Maipo River Basin of Central Chile, which faces exacerbated water stress. We found that ECOSTRESS ESI varies substantially based on the overpass time, with ESI values being systematically higher in the morning and lower in the afternoon. We also compared variations in ESI against spatial patterns in the environment. To that end, we analyzed the vegetation greenness sensed from Landsat 8 and compiled the referential irrigation allocation from Chilean water regulators. Consistently, we found stronger correlations between these variables and ESI in the morning time (than in the afternoon). Based on our findings, we discussed new insights and potential applications of ECOSTRESS ESI in support of improved agricultural monitoring and sustainable water management.<\/jats:p>","DOI":"10.3390\/rs16173174","type":"journal-article","created":{"date-parts":[[2024,8,28]],"date-time":"2024-08-28T03:57:06Z","timestamp":1724817426000},"page":"3174","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["At Which Overpass Time Do ECOSTRESS Observations Best Align with Crop Health and Water Rights?"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9350-8246","authenticated-orcid":false,"given":"Benjamin D.","family":"Goffin","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Virginia, Charlottesville, VA 22904, USA"}]},{"given":"Carlos Calvo","family":"Cort\u00e9s-Monroy","sequence":"additional","affiliation":[{"name":"Centro de Informaci\u00f3n de Recursos Naturales, Providencia, Santiago 7501556, Chile"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5921-5178","authenticated-orcid":false,"given":"Fernando","family":"Neira-Rom\u00e1n","sequence":"additional","affiliation":[{"name":"Centro de Informaci\u00f3n de Recursos Naturales, Providencia, Santiago 7501556, Chile"}]},{"given":"Diya D.","family":"Gupta","sequence":"additional","affiliation":[{"name":"College of Arts and Sciences, University of Virginia, Charlottesville, VA 22904, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7431-9004","authenticated-orcid":false,"given":"Venkataraman","family":"Lakshmi","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, University of Virginia, Charlottesville, VA 22904, USA"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e2009WR007729","DOI":"10.1029\/2009WR007729","article-title":"Agriculture and resource availability in a changing world: The role of irrigation","volume":"46","author":"Sauer","year":"2010","journal-title":"Water Resour.
