Green Space Cooling Effect and Relation to Mitigate Surface Urban Heat Island Effect of Metropolitans Cities of India

Difference Vegetation Index (NDVI) to study vegetation's spatial distribution. However, MODIS thermal bands were employed to analyse Land Surface Temperature (LST) and city thermal properties. The findings show that 15.97% of Lucknow's total area is classified as a High potential SUHI zone, compared to 29.41%, classified as a Low potential SUHI zone. Jaipur has two possible SUHI zones: a high potential zone (12.69%) and a low potential zone (30.45%). In contrast, Ahmedabad exhibits an 18.37 per cent High potential SUHI Zone and a 27.62 per cent low potential SUHI Zone. Delhi exhibits a 14.98 per cent High potential SUHI Zone but is significantly higher at 39.97 per cent Low potential SUHI Zone. Analysis of LST distribution reveals correlations with vegetation cover, with areas abundant in greenery experiencing lower temperatures. This study emphasizes how crucial green infrastructure is to urban planning to improve thermal comfort in fast-urbanizing areas and reduce the negative consequences of urban heat islands.
