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.
