Short summary
This study analyzes 13 years of BC (black carbon) data in China, uncovering patterns in its concentration and sources. Spatial-temporal variations and trends of BC are reported. Our analysis revealed that the reduction rates of BC and its sources varied across different station types, with spatial differences in the drivers of reduction. These long-term observations provide valuable insights to enhance understanding of pollution trends and improve models for predicting air quality.
