GLOBALLY INCREASED CROP GROWTH AND CROPPING INTENSITY FROM THE LONG-TERM SATELLITE-BASED OBSERVATIONS

This research is the first attempt to comprehensively evaluate the recent 2+26 strategy for air quality improvement in Beijing. We additionally considered two corresponding pollution episodes with different emission-reduction strategies to comprehensively understand the effects of 2+26 strategy. The findings suggested that red alerts be employed in heavy pollution episodes to intentionally reduce vehicle exhaust, which has become the dominant source for high PM_2.5 concentrations in Beijing.
