ABSTRACT

Climate maps are required at both national and local scales as the interests of climate issues increase in recent years. To meet the need, this study developed a method of producing temperature maps with automatic weather system (AWS) data provided by Korean Meteorological Agency and Landsat 8 thermal infrared sensor (TIRS) imagery. The results were compared with those from the other conventional methods such as spatially interpolated outcomes of AWS data and land surface temperature extracted from Landsat TIRS imagery. It was found that the propose method is superior to the other two approaches in accurately estimating a spatially-continuous temperature map. Therefore, it is anticipated that the incorporation of AWS data with satellite thermal infrared imagery contributes to generating regional-scale climate maps in an accurate fashion.
