In this study, we collected daily weather variables (precipitation, temperature, wind speed, cloud cover, surface pressure, and humidity) and urban environmental Contexts (non-tree green spaces, settlement surface, population density, urban activity intensity (nightlight data) and impervious) as control variables. All is shown in this Table.<br>

本数据集对应论文《城市树木在缓解社交媒体（social media）上个体负面情绪中的作用》。本次测量的负面情绪值取值区间为0至100，其中0代表极强积极情绪，100代表极强负面情绪。本研究收集了每日气象变量（降水量、气温、风速、云量、地表气压与湿度）以及城市环境背景变量（非树木绿地、建成地表、人口密度、城市活动强度（夜光数据（nightlight data））与不透水面（impervious surface））作为控制变量（control variables）。全部内容详见下表。
