Discovering, understanding, and quantifying the processes that control the chemical makeup of Earth's atmosphere to better understand its future – and ours

Chemical Sciences Division

Climate Change

Earth's atmosphere is changing. CSD scientists work in the lab, in the field, and with computer models to understand how those changes will affect climate. Read More...

Air Quality

CSD researchers study the chemical and physical processes that affect air quality, to better understand and forecast pollution events and trends that threaten human health. Read More...

Ozone Layer

People have harmed Earth's protective ozone layer by releasing ozone-depleting chemicals into the atmosphere. CSD scientists are international leaders in the scientific understanding of stratospheric ozone depletion – and ozone recovery. Read More...
