The rapid urbanisationRapid urbanizationand land use/land coverLand use land cover (LULC) changes have resulted in the unsustainable growthGrowth and rise in heat islands (UHIUrban Heat Island) in Indian cities. PalakkadPalakkad is one such city in Kerala, which is known for its relatively higher temperaturesTemperature than other parts of the state. Therefore, this study was designed to quantify the Land Surface TemperatureLand Surface Temperature (LST) (LST) dynamics of PalakkadPalakkad city in response to the LULC changeLanduse and landcover change during 2001–2021 using temporal Landsat datasetsLandsat dataset. Landsat Imagery 7 and 8 of 2001 and 2021 for summer and winter months were processed. The analytical outcomes reveal that mean LSTLand Surface Temperature (LST) for winter season was 27.07 °C during 2001 and that has increased to 28.35 °C during 2020. Whereas in summer, the mean LST that was 28.59 °C in 2001 has escalated to 29.32 °C during 2021. The results also display a significant decline in vegetation cover from 13.4 to 2.48 km2 and doubling of built-up areas, i.e. from 7.53 to 16.05 km2 during 2001–2021. Similarly, the areas under water bodies have shrunken from 2.18 to 1.14 km2 during 2001–2021. Further, the difference in the rise in the mean land surface temperatureLand Surface Temperature (LST) during the years 2020 and 2001 is more (1.99 °C) during summer season than winter season (1. 28 °C). Diurnal temperature range in LSTLand Surface Temperature (LST) between 2001 and 2020 LST has increased slightly during winters and decreased (−0.37 °C) during summers. Significant rise in day and night temperatureTemperature is likely in future under RCP 4.5 scenario.
