Observation Experiments and Analysis of Summer Urban Heat Island in Cold Region Based on Low-Altitude Dual-Source Remote Sensing: A Case Study of Zhengzhou University Main Campus

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Rapid urbanization worldwide has exacerbated the urban heat island (UHI) effect. Although studies on UHI effect have already become a hotspot, high-precision UHI investigations in cold regions utilizing remote sensing technologies are still underexplored.
