Dataset File Identification: Fine Particulate Matter PM2.5 Mass Concentration Dataset in Tianjin, Beijing-Tianjin-Hebei Region, China (2013); (1 single file). This file contains one hourly average PM2.5 concentration record table for the year 2013, which includes concentration measurements of atmospheric fine particulate matter PM2.5 at a regional background site. The core objectives of developing this dataset are: 1) To study the long-term variation patterns of atmospheric fine particulate matter at the background site; 2) To provide basic parameters and validation data for model simulations and satellite retrievals of the temporal and spatial distribution of atmospheric aerosols; 3) To offer accurate foundational scientific datasets for relevant research teams. Data was collected in 2013. The data collection location is Tianjin, 39°07' North latitude and 117°21' East longitude. This dataset falls within the scope of atmospheric science. The total data volume of all tables is approximately 0.63 MB. This database is categorized as attribute data and is updated irregularly.
