In this study, we aimed to provide experimental data to validate CFD for pollutant diffusion around buildings in non-isothermal flow. We developed a system for simultaneously measuring fluctuating velocity, temperature and concentration. The system compensates for the contribution of temperature to output voltage of a split film with a cold wire. We made a calibrator for a split film for different temperatures and proposed calibration equations for it, and it showed good performance. These equations can be used to simultaneously measure wind velocity and temperature around buildings in non-isothermal flow. We used a high speed flame ionization detector to measure concentration simultaneously with wind velocity and temperature, enabling us to provide turbulence statistics such as heat flux and concentration flux.
