For our research study, temperature level and moisture sensing units were tactically put in the Cairns CBD to stand for people's experience of weather condition at road degree. These tape-taped temperature levels regularly greater compared to the Bureau of Meteorology (BoM) recordings, getting to 45°C at some factors.
