The development of a human thermal comfort assessment model using Geographic Information Systems

Abstract

This research presents a method for creating a wet-bulb temperature map. Wet-bulb temperature is a key indicator for assessing human heat sensation, calculated from dry-bulb temperature and relative humidity data from the Meteorological Department's weather stations nationwide on April 1, 2023. A point-based map was created, converting statistical data into qualitative and spatial point-based data (3x3 km grid). This data is presented statistically and spatially according to Thailand's administrative boundaries at the provincial, district, and sub-district levels. A time-based wet-bulb temperature map was also generated using 3-hourly data of the aforementioned factors, providing wet-bulb temperature information in all aspects. Details of the map creation process and the resulting map images are explained in the content and conclusion sections of this research. It is possible to create a wet-bulb temperature map showing both statistical and spatial information covering the entire country of Thailand.
