Our Vision is a nation that has the needed scientific understanding and information about our atmosphere (environmental intelligence) to make optimal decisions in the interests of the well being of current and future generations.

Chemical Sciences Division


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...
