ASSESSMENT OF LAND SURFACE TEMPERATURE USING REMOTE SENSING TECHNIQUES OVER BIRNIN KEBBI LOCAL GOVERNMENT AREA, KEBBI STATE

Abstract

The Land Surface Temperature (LST) variations in Birnin Kebbi Local Government Area, Kebbi State, Nigeria, was evaluated in this study using data from the Landsat 8 satellite. Top of Atmospheric Radiance (TOP), Top of Atmospheric Brightness, Normalized Difference Vegetation Index (NDVI), Proportional Vegetation (PV), Emissivity, and Conversion from At-satellite Temperature to Land Surface Temperature are among the pre-processing and acquisition of Landsat 8 imagery that is required for the research. According to the results, March has the highest temperature range, ranging from 30.6°C to 42.9°C. Even though some locations within the urban area are relatively warm with temperatures between 31.7°C and 34.4°C, it also reveals that December has the lowest temperature range, ranging from 24.2°C to 34.4°C. These areas include waterlogged, vegetative, rural, and suburban areas. This could be attributed to the natural weather conditions. The study creates comprehensive maps of LST zones, offering important information for a sustainable environment in Kebbi State's Birnin Kebbi local government area. This study demonstrates how well remote sensing and GIS technologies work together to address resource management and environmental issues in semi-arid areas. Thus, it is recommended to create protected areas for the preservation of wildlife and vegetation.
