Spatial dynamics of micro-urban heat islands and satellite-derived indices of Ahmedabad City, India

Urban Heat Island (UHI) is a phenomenon that significantly affects the environment, the cities' liveability, and the citizens' well-being. This study aims to perform a comparative study of the microclimate and UHI phenomenon of Ahmedabad City using MODIS and Landsat Satellite Datasets. The satellite datasets were utilized to calculate the UTFVI, NDBI, MBI, MNDWI, and NDWaI to study the city's heat islands and land surface characteristics. The study's findings reveal that Ahmedabad has 35.53% of the total area classified as having a low potential and 13.55% is designated as a high potential UHI zone for 2023. This study highlights the importance of mitigating the UHI phenomenon in urban centres for the overall well-being of city dwellers. It will help policymakers and stakeholders comprehend plans and take initiatives to minimize the effects of the UHI phenomenon on rapidly growing cities.
