Regional Chemical Modeling

The Regional Chemical Modeling program conducts research on atmospheric composition and its controlling processes aimed at improving air quality, weather and climate prediction. RCM researchers use atmospheric models and observations collected on the ground, in the air, and from space to develop and evaluate innovative ways of describing and simulating the emissions, transport, and chemical evolution of atmospheric pollutants. Scientists in RCM play key roles in International Global Atmospheric Chemistry (IGAC) activities, including the Global Emissions InitiAtive (GEIA) and the Tropospheric Ozone Assessment Report (TOAR), and they work to advance the role of atmospheric composition in the Unified Forecast System and in NOAA's Geostationary Extended Observations (GeoXO) mission.

Research Highlight: The Global Burden of Disease (GBD) is a critical resource for informed policymaking, with the goal of providing a tool to quantify health loss from hundreds of diseases, injuries, and risk factors, so that health systems worldwide can be improved and disparities can be eliminated. CSL scientists contributed to the ambient ozone mortality estimates by producing a series (1990-2017) of global maps of surface ozone concentrations based on all available observations (provided by the Tropospheric Ozone Assessment Report (TOAR)) and output from six global atmospheric chemistry models.
