Assessment of Urban Heat Islands Effect and Land Surface Temperature of Noida, India by Using Landsat Satellite Data

Abstract

The urbanisation is a process of change in land use by construction activities. Therefore, during construction, uses of low albedo materials give rise in heat absorption capacity that becomes the primary cause of alteration of local climate. Additionally, alteration of land use, viz. conversion of vegetation/forested land into urban built-up land and establishment of heavy industrial units contributes pertinently in local heat budget which leads to the formation of urban heat islands (UHIs). Therefore, the adverse impact of UHIs affected not only ecology and local climate but also socioeconomic setups. In the present work, spatial distribution of UHIs and their causal relationship with land use over NOIDA (New Okhla Industrial Development Authority) city has reported. The data pertaining to study was collected from Landsat-8 OLI–TIRS (operational land imager and thermal infrared sensor) sensor. The results show that two clusters were developed in north and mid-east part of the city due to concentration of high-density building and industrial units. It is recommended that development authority should take environmental concern into consideration before planning industrial land use.
