AirPCM-d and AirPCM-h are our curated daily and hourly datasets, respectively.Two datasets both contains the six major pollutants (PM2.5, PM10, O3, NO2, SO2,and CO), Air Quality Index (AQI) calculated according to MEP-2012 standard of China, and the meteorological variables (temperature, pressure, humidity, wind speed, and wind direction). Specifically, the AirPCM-d dataset provides daily records of air pollutants and meteorological variables from 156 monitoring stations across China, covering the period from 2 January 2015 to 12 April 2025. This dataset supports long-term air quality forecasting at a national scale. The AirPCM-h dataset, contains hourly measurements of air pollutants and meteorological variables from 453 monitoring stations worldwide, including 55 in Europe, 35 in the United States, and 363 in China, spanning from 17 January 2024 to 17 April 2025. This dataset enables global-scale multi-pollutant air quality forecasting across diverse climatic regions.
