Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Pollution from ships creates lines of clouds that can stretch hundreds of miles. The calculated concentration of cloud droplets without emissions along the shipping route (yellow line).

New statistical method to detect ozone pollution hot spots and monitor instrument failure; combining PCA and MEWMA

Green Car Congress

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. Sun and her colleagues also hope to apply their data analysis techniques to dust pollution, another major environmental issue in Saudi Arabia.

ICL, CMU study associates PM2.5 air pollution in US with >30,000 deaths and reduced life expectancy

Green Car Congress

These particles are mainly emitted from automobiles, power plants and industry, and known to be hazardous to health. The amount of this fine particle pollution in the US has declined since 1999. The team then combined this with death counts from the National Center for Health Statistics. µg/m 3 and 13.2 concentration of 2.8
