Source Apportionment of Fine Particulate Matter in Wuhan: Application of Rolling Positive Matrix Factorization Under Different Seasons and Episodic Events

Source Apportionment of Fine Particulate Matter in Wuhan: Application of Rolling Positive Matrix Factorization Under Different Seasons and Episodic Events

Abstract Introduction Source apportionment of fine particulate matter (PM2.5) from positive matrix factorization (PMF) model with long-term measurements of chemical composition data can be biased due to changes of source profiles across the sampling period. Rolling PMF strategy with source profile c...
