Rapid urbanization with the changes in land use patterns has resulted in the human induced urban heat island (UHI). UHI is a well-known phenomenon in which urban environments retain more heat than nearby rural environments effecting the urban population. City-heat interacts with rising summer temperatures and heat-waves and emission produced placing additional pressure on infrastructure. This study investigates the impact of interactive influence of Urban Heat Island and Urban Pollution Island (UPI) in two major cities of India (Delhi and Bangalore). The seasonal study for summer was performed for the two cities and so that interactive influence of aerosol, Nitrogen dioxide (NO ₂ ) and Land Surface Temperature (LST) is measured when the effect of UHI is the most. The study is performed for five years (2019, 2020, 2021, 2022 and 2023) and it was observed that in Delhi the overall aerosol index is greater …
