Description
Satellite data is a cost-effective and easily accessible information source that is widely used in a variety of applications. When it comes to temperature data, satellites receive thermal electromagnetic energy emitted by the earth’s surface from which surface temperature is empirically derived. Despite such data being a relatively accurate representation of surface temperature, it does not necessarily replicate the true air temperature patterns of a place. Depending on the type of data used, research studies can arrive at considerably different outcomes, and subsequently induce different public policies related to heat extremes, especially in cities. In this project, relations between surface temperature and air temperature during unusually hot summer days are examined for the City of Richmond, Virginia, a mid-sized city located in the Southeast Climate Region. This is achieved by comparing satellite-derived surface temperatures from Landsat 8 imagery retrieved on 22nd August 2017 to air temperatures collected in the field (from thermistors mounted on bicycles and cars) and modelled on 13th July 2017. Three types of comparisons are made, in which the 2 variables demonstrate considerable differences aiding understanding of the limitations of Landsat 8-derived temperatures. Subsequently, this will help further research seeking to inform the identification of populations vulnerable to the Urban Heat Island effect within the City of Richmond. This is an important contribution to the development of public policy responses to Urban Heat Island phenomena.
