The Role of the Urban Green Space Density in Determining the Temperature Humidity Index of an Indonesian Main City

Abstract:

Global warming due to increased activity of the city center from time to time raises the risk of a rise in temperature, but the urban green space can provide a micro-climate control and thermal comfort. This study analyzes the spatial distribution of thermal comfort, based on the method Temperature Humidity Index (THI) and using satellite imagery 2B recording Sentinel February 20, 2019, to obtain information about the density of the vegetation. Relationships between  density urban green space with THI were  assessed using linear regression with a sample of 117 in one of the major cities of  Indonesia. The thermal comfort of urban green space tends to become uncomfortable due to  open land and undeveloped land. The density of vegetation on urban green space  has a significant  influence on the decrease in THI.
