Dr. Bryan Duncan

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.

Tiger Teams

Bryan contributes to or leads the following Tiger Teams:

• Satellite-Evaluated and Satellite-Informed O3 Distributions for Estimating US Background O3, led by Jessica Neu.
• Supporting the Use of Satellite Data in Regional Haze Planning, led by Arlene Fiore.
• Using Satellite Remote Sensing to Derive Global Climate and Air Pollution Indicators, led by Susan Anenberg.
• Supporting the Use of Satellite Data in State Implementation Plans (SIPS), led by Arlene Fiore.
• Co-leads, along with Jason West, the Tiger Team Demonstration of the Efficacy of Environmental Regulations in the Eastern US.
