Meteorological observation data under UV parasol, street trees, dry-mist spraying, and direct sunlight

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).

本数据集记录了在紫外线遮阳伞、街道树木、干燥雾喷淋以及直射阳光下的气象观测数据。观测于2021年8月5日日本标准时间11:40至15:50之间，在日本茨城大学茨城校区进行。各测量点之间相距约8米。使用的标准紫外线遮阳伞为黑色聚酯材质（100%，背面进行溅射处理），伞骨长度为0.58米。街道树木为高11米的三角枫（Acer buergerianum）。干燥雾具有以下特性：水流量为1.3升/分钟，颗粒尺寸约为20微米，喷淋覆盖面积为1.5平方米。干燥雾从距离地面2米的高度向下喷淋。采用TR-5106仪器观测了距离地面1.5米处的空气温度和黑球温度，使用HHB-3101（T&D Corporation）仪器观测了相对湿度。风速和风向在距离地面2.0米处通过Vantage Pro（Davis Instruments）仪器进行观测。表面温度则通过R300SR-S热像仪（Nippon Avionics）进行测量。
