Snippet: which explains some of the positive anomalies in this period. Since much of the long-distance 103 dust transport takes place above the boundary layer (10), these AOD anomalies do not 104 necessarily represent ground-level PM2.5 trends. The same is true for satellite-measured O3, 105 which is strongly influenced by its generally increasing abundance above the boundary layer, 106 especially during winter. 107 108.....
