Climate change and surface urban heat islands in jakarta: analysis of landsat data and ground observations / Rufaidha Lathiifunnisa

Abstrak
Climate change has led to an increase in global air temperatures posing a threat to the liability of capital cities. This study focuses on understanding the Surface Urban Heat Island (SUHI) phenomena which occurs over cities and is exacerbated by climate change. Spectral indices derived from Landsat data were used to understand SUHI while trends in air temperature precipitation and relative humidity were analyzed using ground observation data collected from 1992 to 2022 in the capital city of Indonesia Jakarta. The spectral indices used were the Normalized Difference Vegetation Index (NDVI) Enhanced Vegetation Index (EVI) Soil Adjusted Vegetation Index (SAVI) and Normalized Difference Moisture Index (NDMI). Land Surface Temperature (LST) was used to represent SUHI. Results indicate that NDMI has the highest Pearson rsquo s correlation coefficient with LST (-0.73) followed by EVI (-0.41) SAVI (-0.4) and NDVI (-0.4). Trend analysis using Mann-Kendal test and Sen rsquo s Slope showed a statistically significant increase in air temperature with a slope estimation of 0 03 deg C per year while rainfall and relative humidity did not significantly differ over 30 years. SUHI trend analysis showed a statistically significant increase with a slope estimation of 0 1 deg C from 1992-2022. Mean surface temperature increased from 38.9 deg C in 1992 to 39.4 deg C in 2022. Jakarta s surface temperature ranged from 24 deg C ndash 57 deg C across water bodies vegetation bare land urban and industry analyzed using Support Vector Machine. This study provides insight into the condition of SUHI over time allowing the government to make efforts to mitigate the impact of climate change.
