The phenomenon is evaluated through the SUHI intensity, which is the difference in temperatures between urban and non-urban areas. In this study, we assessed the spatial and temporal dynamics of SUHI in two urban areas of the French Guiana, namely Ile de Cayenne and Saint-Laurent du Maroni, for the year 2020 using MODIS-based gap-filled LST data. Our results show that the north and southwest of Ile de Cayenne, where there is a high concentration of build-up areas, were experiencing SUHI compared to the rest of the region. Furthermore, the northeast and west of Saint-Laurent du Maroni were also hotspots of the SUHI phenomenon. We further observed that the peak of high SUHI intensity could reach 5 \u00b0C for both Ile de Cayenne and Saint-Laurent du Maroni during the dry season when the temperature is high with limited rainfall. This study sets the stage for future SUHI studies in French Guiana and aims to contribute to the knowledge needed by decision-makers to achieve sustainable urbanization.<\/jats:p>","DOI":"10.3390\/s24061931","type":"journal-article","created":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T04:25:15Z","timestamp":1710735915000},"page":"1931","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Spatial and Temporal Variation of Urban Heat Islands in French Guiana"],"prefix":"10.3390","volume":"24","author":[{"given":"Gustave","family":"Ilunga","sequence":"first","affiliation":[{"name":"ESPACE-DEV (Espace pour le D\u00e9veloppement), University of La R\u00e9union, University of Montpellier, Institut de Recherche pour le D\u00e9veloppement (IRD), University of Antilles, University of French Guiana, 97300 Cayenne, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4063-8418","authenticated-orcid":false,"given":"Jessica","family":"Bechet","sequence":"additional","affiliation":[{"name":"ESPACE-DEV (Espace pour le D\u00e9veloppement), University of La R\u00e9union, University of Montpellier, Institut de Recherche pour le D\u00e9veloppement (IRD), University of Antilles, University of French Guiana, 97300 Cayenne, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0283-9558","authenticated-orcid":false,"given":"Laurent","family":"Linguet","sequence":"additional","affiliation":[{"name":"ESPACE-DEV (Espace pour le D\u00e9veloppement), University of La R\u00e9union, University of Montpellier, Institut de Recherche pour le D\u00e9veloppement (IRD), University of Antilles, University of French Guiana, 97300 Cayenne, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Zermani","sequence":"additional","affiliation":[{"name":"ESPACE-DEV (Espace pour le D\u00e9veloppement), University of La R\u00e9union, University of Montpellier, Institut de Recherche pour le D\u00e9veloppement (IRD), University of Antilles, University of French Guiana, 97300 Cayenne, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0642-1925","authenticated-orcid":false,"given":"Chabakata","family":"Mahamat","sequence":"additional","affiliation":[{"name":"ESPACE-DEV (Espace pour le D\u00e9veloppement), University of La R\u00e9union, University of Montpellier, Institut de Recherche pour le D\u00e9veloppement (IRD), University of Antilles, University of French Guiana, 97300 Cayenne, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,18]]},"reference":[{"key":"ref_1","first-page":"31","article-title":"Material dependence of cities and implications for regional sustainability","volume":"1","author":"Liu","year":"2020","journal-title":"Reg.
