UNC podcast: Climate change and air pollution
Featuring HAQAST PI Jason West
‘Each year, millions of people die from exposure to air pollution. And if unaddressed, climate change could bring those numbers up even higher by the end of the century.’
MILLER PUBLISHED A PIECE IN PHYSICS TODAY PROFILING HAQAST
Featuring HAQAST Member Daegan Miller
‘“Out of sight, out of mind” goes the common saying, yet what people can’t see can have an important impact on their well-being. Invisible gases including nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone negatively affect human health, and satellites offer the best means of tracking those atmospheric pollutants.’
Featuring HAQAST PI Jason West
‘The USA will benefit from improved air quality in the future, through actions to reduce greenhouse gas (GHG) emissions both domestically and globally.’

Fiore and Jin’s Research Featured as NASA Image of the Day
Featuring HAQAST PI Arlene Fiore
‘Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog and a primary cause of poor air quality. 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.’
