Assessing Spatiotemporal Thermal Dynamics and Aridity Patterns through Multi-Sensor Remote Sensing Integration

Abstract This study introduces a versatile framework for tracking how heat and dryness change over time and space by combining various satellite data sources within Google Earth Engine. Using high-resolution MODIS temperature records from 2024, we examined Land Surface Temperature (LST) trends after filtering out low-quality data from both day and night readings to maintain accuracy. To better understand how the landscape holds onto energy and moisture, we measured thermal intensity through the daily temperature swing (ΔLST). In tandem, we used 2020 surface reflectance data to calculate the Solar-Based Aridity Index (SBAI). This process required cleaning the data of cloud interference and calculating the specific amount of solar radiation reaching the ground (Rs) based on light spectrums and the sun's position. By categorizing these SBAI results into zones-from extremely dry to humid-we created a clear map of environmental stress. Finally, by linking these heat patterns to land-use types, the research reveals how different terrains shape local climates and vulnerability to drought. Ultimately, the study proves that merging different MODIS datasets offers a powerful, adaptable way to monitor ecological decline and climate-driven drying, providing vital information for smarter land management and climate resilience.
