In Situ Microclimate Data in Nanchang Fishtail Park: An Urban Ecological Park

The dataset consists of measurements from 19 observation points distributed across three principal elevation zones: the street-edge zone (about 20.05 m), the intermediate terrace (about 18.50 m), and the central basin (about 16.50 m). Points were selected to represent contrasts in openness, vegetation cover, and surface material, thereby capturing the park’s spatial diversity. At each point, ten variables were recorded: • Air temperature (Temp, °C);• Relative humidity (RH, %);• Wind speed (Wind, m/s);• Ambient noise (Noise, dB);• Elevation (ELE.A, m);• Openness (OL.P, %);• Vegetation number (VN, count);• Water ratio percentage (WR.P, %);• Hardscape ratio percentage (HS.P, %);• Distance to center point (DCP, m). Measurements were taken at 09:00, 14:00, and 19:00 during July–August 2023, representing morning, mid-afternoon, and early evening conditions when microclimatic contrast is most evident.本数据集包含分布于三个主要海拔分区的19个观测点的实测数据，三个分区分别为街旁带（约20.05 m）、中间台地带（约18.50 m）与中心盆地区域（约16.50 m）。观测点的选取兼顾了开阔度、植被覆盖度与地表材质的差异，以充分表征该公园的空间多样性特征。每个观测点共记录10项变量： • 空气温度（Air temperature，缩写Temp，单位：°C）； • 相对湿度（Relative humidity，缩写RH，单位：%）； • 风速（Wind speed，缩写Wind，单位：m/s）； • 环境噪声（Ambient noise，缩写Noise，单位：dB）； • 海拔高度（Elevation，缩写ELE.A，单位：m）； • 开阔度（Openness，缩写OL.P，单位：%）； • 植被数量（Vegetation number，缩写VN，单位：count）； • 水域占比（Water ratio percentage，缩写WR.P，单位：%）； • 硬质铺装占比（Hardscape ratio percentage，缩写HS.P，单位：%）； • 至中心点距离（Distance to center point，缩写DCP，单位：m）。 本次实测于2023年7月至8月的09:00、14:00及19:00开展，分别对应清晨、午后中段与傍晚时段——此时公园微气候差异最为显著。
