Short summary
We quantify the contribution of long-range transport to PM levels in the NW-IGP through back-trajectory climatology analysis. Transport from the west significantly enhanced coarse- and fine-mode PM mass loadings during all seasons. Local pollution episodes enhanced coarse-mode PM only during winter and fine-mode PM during winter and summer seasons. South-easterly air masses (source region: SE-IGP) were associated with significantly lower fine- and coarse-mode PM mass loadings during all seasons.
