In recent decades, the Chinese government has duction ranges from −5 to −15 % in the NCP, with a max- made a great effort in initiating large-scale ecological imum reduction of −12:4 % (−19:2 µg m−3/ in BTH and restoration programs (ERPs) to reduce the dust concentra- −7:6 % (−10:1 µg m−3/ in the NCP. We find the dust plumes tions in China, especially for dust storm episodes.
