Atmospheric Chemistry Division (ACD), 2013 - 2016

ACD’s research focuses on advancing understanding and predictive capability for atmospheric composition and related processes. Research is organized around two major themes – Air Quality Prediction and Weather-Chemistry-Climate Interactions – and includes for example, a focus on issues related to the interaction of anthropogenic and biogenic chemical emissions, the effects of wildfires on air quality, and the impacts of upper troposphere/lower stratosphere (UT/LS) and middle atmosphere composition on climate. The synthesis of observations with atmospheric chemistry models is central to progress, with a focus on understanding and modeling fundamental processes. ACD scientists work closely with the wider research community, providing intellectual leadership and facility support for measurement capabilities, laboratory and field experiments and community atmospheric chemistry models. ACD was at various times part of the Earth-Sun Systems Laboratory (ESSL) and the NCAR Earth System Laboratory (NESL). The Atmospheric Chemistry Division (ACD) became the Atmospheric Chemistry Observations and Modeling (ACOM) Laboratory in 2015.
