Annmarie Eldering, Ph.D., is a member of the Greenhouse Gas Measurement Program at the National Institute of Standards and Technology. She joined NIST in 2022 after over 20 years at the NASA Jet Propulsion Laboratory. Her expertise is in satellite remote sensing of greenhouse gases and air pollutants. She served in scientific and technical leadership roles for the last 15 years at JPL, including 12 years as the Deputy Project Scientist for the NASA Orbiting Carbon Observatory (OCO-2) satellite mission, which observes atmospheric carbon dioxide. At the same time, she was the Project Scientist of NASA’s Orbiting Carbon Observatory-3 (OCO-3), a similar instrument payload on the International Space Station which added CO2 mapping capabilities. Her work at NIST in the Greenhouse Gas Measurement Program focuses on facilitating efforts to better connect satellite remote sensing measurements of CO2 and CH4 to international standards. She is also engaging in efforts to refine observational, modeling, and data assimilation capabilities so that GHG information more effectively meets the needs of users ranging from industry to cities and states and national governments.
