Satellite-Based Air Temperature and Heat Index of Minna Town and Metropolis, Niger State, Nigeria
This study examined satellite-based air temperature and heat index of Minna town and metropolis, Niger state, Nigeria. Urban warming is capable of causing rise in water temperature, high energy consumption, increase in heat related ailments and death of aquatic organism. The investigation generated satellite air temperature data imageries and corresponded the records to heat index. The result showed that in 1990, air temperature concentrated all-round the surface of Minna city and environs having maximum range of 300C. In the year 2000, air temperature concentrated in the eastern segment of the city having maximum temperature of 290C 9. Also, in 2022, air temperature concentrated in the north and north-eastern part of Mnna city and environs recording temperature of 310C. It revealed that heat cramps and heat exhaustion were likely; heat stroke was probable with continued activity. The rise in air temperature and LST was due to increased human activities that devastate the vegetation cover of Minna surface area and rise in urban pavement materials that trap heat to the urban canopy and gradually release it to the environment. Therefore, it is recommended among others for the city dwellers and government to begin intensive tree planting and urban greeting in order to mitigate the impact of urban heat effects in the metropolis of Minna.
