Title: Elevation-Wise And Direction-Wise Distribution Of Land Surface Temperature in Jeju Island Using Landsat Data
Abstract:
In the present study thermal band of Landsat 8 was utilized to estimate the land surface temperature (LST) of Jeju island for winter and summer season to further evaluate the temperature distribution in terms of elevation and directions. Results revealed that temperature varies greatly in the island. In winter season the temperature of island varies from -3.7 oC to 31 oC while in summer season it varies from 20.6 oC to 43.1 oC. Therefore, it can be assumed that there will be a significant geographic impact on spatial distribution of temperature. So, to understand the impact, temperature was evaluated in different cardinal directions at 100 m and 500 m elevation. On 100 m elevation it was observed that North and South facing directions have same temperature in winter season but in summer season the North facing direction has 0.97 oC higher temperature as compared to South direction. Similarly East and West facing directions temperature was also compared for both season and it was noted that in winter season East direction has high temperature as compared to West direction but in summer season West direction has higher temperature from East direction. However, on 500 m the results showed that South direction has 0.58 and 1.52 higher temperature over North direction in winter and summer season respectively while West direction has 0.5 and 3.3 higher temperature over East in winter and summer season respectively. From analysis it was also observed that in winter season East and West direction does not have a huge difference in temperature on all elevations but in summer we observed differences in temperature at 500, 1000, and 1500m elevation, likewise South has higher temperature differences in winter above 1000m while in summer season North has higher temperature from South below 500m but above 1000m elevation South has higher temperature over North. Interestingly at the highest point in Jeju all directions have almost same temperature. It revealed that seasons and altitude have great impact on the LST in different cardinal directions of the island. From the results it can be assumed that the island ecological diversity would be strongly related to the geographical distribution of temperature.
