This study evaluated the cooling effects of rooftop gardens on land surface temperature (LST) in Dhaka North City Corporation, Bangladesh, using satellite observations from March to May 2022. Researchers identified 2,012 buildings with rooftop gardens and 43,553 without, deriving daytime LST from Landsat 8 data. Results indicate that rooftop gardens reduce mean rooftop LST by up to 1.99 °C during peak heat in May and suppress extreme rooftop temperatures by 3.9–6.4 °C across the pre-monsoon season, also showing reduced thermal variability.
