Assessing Moisture Content and Its Mitigating Effect in an Urban Area Using the Land Surface Temperature–Vegetation Index Triangle Method

Nowadays, climate change and heat extremes are becoming highly challenging problems in many cities across the globe. One of solutions to overcome this problem is use vegetation, and, particular, extending range overgrown areas, which sometimes referred as “urban green areas.” In paper, moisture condition its mitigating effect on Land Surface Temperature urban areas were examined Warsaw, Poland, using satellite data. To do so, so-called “Triangle Method” was employed. The triangle method based a Temperature–Normalized Difference Vegetation Index (LST-NDVI) scatterplot calculate Dryness (TVDI) modification–quadratic (qTVDI). This article discusses, detail, usefulness for analyses built-up areas. drought indices TVDI qTVDI compared with those LST, NDVI, NDBI (Normalized Building Index). study shows that LST-NDVI analysis promising tool establishing conditions over studying vegetation impact islands. Detailed an area, better agreement LST than classic TVDI.
