This study uses ground-based measurements and satellite data to investigate urban heat island (UHI) effects across five Thailand provinces. We collected land surface temperature (LST) data from different surface types using infrared thermometers and the GLOBE Protocol, comparing urban and rural locations in Nonthaburi, Saraburi, Chiang Mai, Nakhon Ratchasima, and Nakhon Si Thammarat provinces. Our research employed NASA APPEARS platform data to validate ground measurements and analyze broader temperature patterns. Results from satellite data revealed significant temperature variations between urban and rural areas, with maximum daytime and nighttime temperatures of 47.19°C and 31.65°C respectively, observed during the hot season in urban Chiang Mai. Surface type analysis showed that metal roofs and dry ground consistently recorded the highest temperatures of 50.3°C and 49.5°C, respectively, while vegetated areas and water bodies demonstrated cooling effects. This study provides valuable insights into urban planning and heat mitigation strategies in Thailand's rapidly developing cities.
