Hourly monitoring data of air quality at multiple monitoring stations in a certain city in 2021

This dataset comprises high-temporal-resolution environmental monitoring data from a specific region for the year 2021, containing approximately 8,700 hourly records. The data includes complete timestamp information (year, month, day, hour) and multiple environmental parameters, covering meteorological elements and air quality indicators.The data originates from professional environmental monitoring stations, collected continuously through automated monitoring equipment. The dataset has undergone rigorous quality control, with obvious outliers removed and data quality flags annotated. Based on the data characteristics, the monitoring indicators likely include wind speed, wind direction, pollutant concentrations, and other parameters, reflecting the spatiotemporal variation patterns of environmental conditions throughout the year in the region.The data is stored in structured tabular format (e.g., .xlsx or .csv), with each record corresponding to synchronized multi-parameter monitoring results at specific time points. This dataset holds significant value for environmental science research, air quality analysis, climate change studies, pollutant dispersion modeling, and environmental policy formulation, providing high-quality benchmark data for environmental modeling and machine learning algorithms.
