Duncan Bio

Bryan Duncan is a Research Physical Scientist in the Atmospheric Chemistry & Dynamics Laboratory of the NASA Goddard Space Flight Center (GSFC), as well as the Project Scientist for the NASA Aura satellite mission.

Bryan’s HAQAST team is developing a multi-pollutant Health Air Quality Index (HAQI) and is applying it to output from the new NASA global air quality forecast system, which wit is helping to evaluate and improve. This system is important as most people around the world have little or no access to air quality information. The forecasted HAQI will communicate the risks of exposure to multiple air pollutants so that people may take action to reduce their exposure. We are currently working with a few city governments, including Rio de Janeiro and Jakarta, to properly message and distribute the forecasts as well as to provide satellite data that may be used to identify where local efforts are needed to reduce emissions. We will also investigate the development of a satellite-based HAQI.

In addition, he is contributing to the following Tiger Teams:

And he co-leads, along with Jason West, the Tiger Team Demonstration of the Efficacy of Environmental Regulations in the Eastern US.
