Abstract
Satellite-derived nighttime land surface temperature (LST) provides unique insights into urban thermal dynamics, such as nocturnal urban heat island effects, differentiated from daytime LST. Recent advances in satellite technology and upcoming missions promise high spatiotemporal resolution nighttime LST, unlocking new opportunities for urban studies. This study presents a comprehensive review of 420 peer-reviewed papers published between 2016 and 2024 to identify the trends in how nighttime LST has been used in the urban application and summarize the progress, key achievements, and current constraints in six main application topics: urban heat island analysis, heat and health impacts, associations with greenspace and air temperature, synergetic usage with numerical models, and other interdisciplinary applications. Based on our review, we suggested five main future directions for nighttime LST studies, including improving nighttime LST data resolution and quality, advancing modeling techniques, expanding geographic and climatic coverage, exploring emerging topics such as anthropogenic heat and nighttime heatwaves, and integrating nighttime LST with multidimensional urban data. Further research using nighttime LST is expected to understand better nocturnal thermal dynamics and their impacts on public health, energy use, and environmental sustainability.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
