EmailSummary: This report explores the dynamics of land surface temperature (LST) in Freetown, Sierra Leone, over the past decade, highlighting significant temperature anomalies and their correlation with land use and land cover changes. The research conducted by AKADEMIYA2063 focuses on identifying regions with pronounced temperature divergences and understanding the factors driving these changes.
- Data Collection: The study utilizes satellite imagery and ground-based temperature measurements from 2013 to 2023 to analyze LST patterns across Freetown and its surrounding areas.
- Urban Heat Island Effect: The report identifies the urban heat island effect as a significant contributor to temperature anomalies, particularly in densely populated and built-up areas.
- Land Use and Cover: Changes in land use and land cover, such as deforestation, urbanization, and agricultural expansion, are examined to understand their impact on local temperature dynamics.
The findings emphasize the need for sustainable urban planning and green infrastructure to mitigate the urban heat island effect and enhance climate resilience. The report concludes with recommendations for policymakers, including promoting green spaces, improving building regulations, and enhancing climate monitoring systems.
