Assessment of Land Surface Temperature across the Niger Delta Region of Nigeria from 1986-2016 using Thermal Infrared Dataset of Landsat Imageries

Abstract
The Niger Delta region of Nigeria has been the sole oil producing basin since the discovery of oil in commercial quantity in 1965. Gas flaring, oil pipeline vandalism and anthropogenic activities has caused severe eco-environmental changes in the region. This alteration has caused unquantifiable changes to land surface temperature in the region hence, the need to investigate it. The aim of this research was therefore to investigate the historical Land Surface Temperature (LST) dynamics of the entire Niger Delta region of Nigeria from 1986 to 2016 using Thermal Infrared Dataset of Landsat Imageries. Landsat 5(TM), Landsat 7 (ETM+) and Landsat 8 (OLI) images of 1986, 2002 and 2016 were downloaded from NASA Earth Observatory website and used for this research. Image processing was carried using ERDAS IMAGINE and ENVI software. ArcGIS software were used to build model for LST estimation. The results showed that as at 1986 the minimum LST was 19.4 ⁰C while the maximum LST was 29.89⁰C but in 2002 it increased to minimum of 19.8⁰C while the maximum temperature rose to 30.9⁰C and in 2016 it ranges further increased to lowest of 19.9⁰C and maximum of 31.1⁰C. On the overall, LST increased by 1.21⁰C across the study area. This result therefore has confirmed the assertion of climate change in the region.
