New research published in the journal Atmospheric and Oceanic Science Letters reports significant progress in studying the relationship between meteorological conditions and atmospheric fine-particle (PM_2.5) concentrations. In this new study, meteorological fields were obtained using two sets of data to analyze the differences in the simulated PM_2.5 concentration. Results showed that the meteorological field had a strong influence on the concentration levels and spatial distribution of the simulated pollution. Also, one of the data sources resulted in relatively smaller simulation errors, allowing more accurate modeling of PM_2.5 concentrations.
