Satellite-Based Analysis of Extreme Land Surface Temperatures and Diurnal Variability Across the Hottest Place on Earth

A recent satellite-based analysis reveals that the Lut Desert in Iran, already recognized as one of the hottest places on Earth, experiences even more extreme land surface temperatures (LST) than previously documented. Using advanced MODIS-derived LST data with improved accuracy and higher spatial resolution, researchers identified a record LST of 80.83 °C in 2018—approximately 10 °C hotter than the previous record. The study also highlights the Lut Desert's remarkable diurnal temperature variability, which can reach up to 71 °C depending on the season. This research provides critical insights into land-atmosphere interactions in extreme environments and offers a deeper understanding of how such conditions may evolve in a warming world.
