Dr. Bryan N. Duncan is an atmospheric scientist in the Atmospheric Chemistry and Dynamics Laboratory (ACDL) at NASA Goddard Space Flight Center. He is Project Scientist for the NASA Aura satellite mission, which observes atmospheric constituents in the troposphere, stratosphere and mesosphere. He has expertise in tropospheric trace gas composition with special interests in observing strategies and technology requirements for monitoring the tropospheric hydroxyl radical (OH) as well as other trace gases.
