Atmospheric particulate nitrate is relevant to various atmospheric processes and shows profound impacts on regional air quality global climate change. Exploring the formation mechanism sources of in matter essential for successful mitigation nitrate. This review summarises different mechanisms, sources, source apportionment methods In particular, current progress nitrogen/oxygen (N/O) isotope t...

In this work, the Weather Research Forecast (WRF)–Sparse Matrix Operator Kernel Emission (SMOKE)–Comprehensive Air Quality Model with Extensions (CAMx) modeling system with particulate source apportionment technology (PSAT) module was used to study and analyze the source apportionment of sulfate and nitrate particulate matter in the Pearl River Delta region (PRD). The results show that superreg...
