Arlyn Andrews leads the Carbon Cycle Greenhouse Gases group within NOAA’s Global Monitoring Laboratory. She has measured carbon dioxide from Earth’s surface to the stratosphere using a variety of diverse platforms, including NASA’s ER-2 aircraft -- a modified U-2 spy plane, high-altitude balloons, and very tall broadcast towers. Arlyn earned her Ph.D. in Earth and Planetary Science from Harvard University in 2000 and then spent a few years at NASA Goddard Space Flight Center, where she contributed to the initial development of concepts for active and passive CO2 satellite sensors.
Arlyn joined the NOAA Global Monitoring Laboratory in 2003 and assumed responsibility for in situ measurements from tall towers within the NOAA Global Greenhouse Gas Reference Network. She developed the NOAA’s CarbonTracker-Lagrange regional modeling framework for estimating greenhouse gas emissions and removals, with a particular emphasis on understanding uptake of carbon dioxide by terrestrial ecosystems. Arlyn has been an active participant in the U.S. Interagency North American Carbon Program since its inception. She served on the Climate Variability and Change panel supporting the Decadal Survey for Earth Science and Applications from Space (ESAS 2017), and she is a member of the NASA Carbon Monitoring System Science Team and the NASA Orbiting Carbon Observatory Science Team.
