Aura OMI Aerosol Index (AI) distribution over East China on (a) 20 April 2011, (b) 23 April 2011, and (c) 26 April 2011. Three-day back-calculated trajectories starting at Wuhan (30.5°N, 114.4°E) from 1000UTC on (d) 22 April 2011 (at 0.5 km, 2 km, 3 km, 6 km, and 7 km), (e) 25 April 2011 (at 1 km, 2 km, 3 km, 4 km, and 6 km), and (f) 28 April 2011 (at 1 km, 2 km, 3 km, 4 km, and 5 km), using the HYSPLIT model. The time-height display for the calculation of (d), (e), and (f) is shown in (g), (h), and (i), respectively.
