Analysis of Urban Heat Temperature and Day/Night Temperature Variation in Jakarta City Using Remotely Sensed Data

Thermal satellite sensor images are widely used for identifying the environment temperature mainly in urbanized areas. The Thermal Infra Red Sensor (TIRS) onboard Landsat-8 contains two thermal bands, which measure land surface temperature (LST) at 30-meter resolution. Thermal band data provide important information about water irrigation, heat, as well as heat island in urban area. By using MODIS satellite also we can assess the day/night LST hence we can comprehend the diurnal temperature variation. In this study the LST that retrieved from satellite data will be used to identify urban heat island (UHI) effect in Jakarta city using Split Windows Algorithm method. As a result we obtain that the UHI area located on area with higher human and industrial activities, especially in central to eastern part of Jakarta. There is a tendency that the border area of Jakarta (east, west and southern part) can transform to be new UHI in the future. From field measurement also we calculate the lowest and the highest temperature is 23.2oC (for vegetation class) and 51oC (for road asphalt) respectively.Hlm.87-9
