Clearer View of Great Lakes Air Quality (NASA Image of the Day)

The complex lake and land breezes and the atmospheric pressure differences across the Great Lakes region of North America can result in high levels of ozone pollution that are difficult to monitor or predict. Recently, air quality experts began incorporating more satellite data and customized models from NASA to better track that pollution. Their goal is to better inform local decision-making about how to improve air quality.

No Breathing Easy for City Dwellers: Particulates (NASA Image of the Day)

Featuring HAQAST PI Susan Anenberg

Air pollution is the fourth leading risk factor for death around the world. But one type of pollutant is particularly harmful: fine particulate matter (PM2.5). These small, inhalable particles (less than 2.5 micrometers in diameter) result from direct emissions into the air, as well as interactions among other pollutants.

The Far-Reaching Consequences of Wildfire Smoke Plumes

Featuring HAQAST PI Jeffrey Pierce

Knowledge of wildfire smoke impacts is critical for researchers and public health experts going forward, as climate change continues to produce a warmer, drier western United States and the fire season is expected to become only longer and more intense. To fill this gap, Jeffrey Pierce and his team looked at smoke exposure across seasons and regions in the United States between 2006 and 2018.

Yet it is not directly measurable from space because of the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. Now NASA-funded researchers have devised a way to use satellites to measure the precursor gases that contribute to ozone formation.’
