Meteorological observation data under UV parasol, street trees, dry-mist spraying, and direct sunlight.
The observation was conducted within the campus of the University of Tsukuba, Tsukuba City, Japan, from 11:40 to 15:50 Japan Standard Time on August 5, 2021. Each measurement point was approximately 8 m away from the next. A standard black-colored UV parasol made of polyester (100%, + sputtering on the back) and with a rib length of 0.58 m was used. The street tree was a trident maple (Acer buergerianum) with a height of 11 m. The dry mist had the following properties: water volume 1.3 L/min, particle size ~20 µm, and area sprayed covered 1.5 m2. The dry mist was sprayed downward from a height of 2 m above ground level (AGL). The air temperature and black globe temperature at 1.5 m AGL were observed using TR-5106 and the relative humidity at 1.5 m AGL was observed using HHB-3101 (T&D Corporation). The wind direction and speed at 2.0 m AGL were observed with a Vantage Pro (Davis Instruments). Surface temperatures were measured using an R300SR-S thermal camera (Nippon Avionics).
