This study looks at how heat, lights, and nature interact in the cities of Los Angeles and San Diego from January to July 2025. Using satellite images, we measured land temperature (LST), how much hotter cities are than nearby rural areas (Urban Heat Island or UHI), light levels at night (NTL), and nature indicators like vegetation, built-up areas, and water (NDVI, NDBI, NDWI).
We found that Los Angeles is generally hotter than San Diego, with more built-up areas and less vegetation. Places with more plants were cooler, while areas with more buildings and lights were hotter. The maps we created show which parts of the cities are more vulnerable to heat.
