Moderate PM2.5 levels in Eastern states;

According to AirNow, PM2.5 levels have cleared out from the West, but the East continues to experience moderate and unhealthy levels for sensitive groups as is the case of Pennsylvania and Maryland (top left). Although the number of fires have reduced significantly in the South, HMS still detected different fires in Florida and Georgia (top right).These fires have not produced significant smoke, however MODIS AOD product retrieved high AOD levels in the Southeast region (bottom right). That could be attributed to the remnant smoke aloft generated on previous days. High AOD levels were also retrieved in Texas (bottom right) which is assumed to be due to local aerosols, unless dust is detected in the next days.

No country in history has become a major industrial power without creating a legacy of environmental damage. China is clearly not an exception. The speed and scale of China's rise has brought an unprecedented pollution problem. Public health is reeling. Pollution has made cancer China's leading cause of death according to the Ministry of Health. Ambient air pollution alone is blamed for hundreds of thousands of deaths each year. The factories and spewing automobile engines recently caused hundreds of flights to be cancelled in and around Beijing. Stores are selling out of face masks and the government struggles to figure out this political challenge and provide relief of the long-term burden on its people.(Images)
