Arlene Fiore

Arlene Fiore is the Peter H. Stone and Paola Malanotte Stone Professor of Earth, Atmospheric and Planetary Sciences at the Massachusetts Institute of Technology (MIT), where she joined the faculty in 2021. She was appointed Associate Department Head for EAPS in 2025. Her career spans roles at Columbia University's Lamont-Doherty Earth Observatory and the NOAA Geophysical Fluid Dynamics Laboratory.

• Harvard University: AB in Environmental Geoscience (1997), PhD in Earth and Planetary Sciences (2003)

Fiore investigates two-way interactions between air pollutants and the climate system, integrating chemistry-transport models, satellite observations, and ground data. Her research addresses:

• Air pollution responses to natural vs. human-caused emissions
• Trends in atmospheric composition
• Atmospheric oxidizing capacity (self-cleansing processes)
• Intercontinental pollutant transport
• Vegetation-atmosphere-climate interactions
• Climate variability's imprint on atmospheric chemistry

Her recent publications focus on tropospheric ozone trends, pollution event dynamics, and oxidizing capacity under climate change. These studies span disciplines like atmospheric chemistry, climate science, and environmental modeling.

Scientific honors include:

• AGU James R. Holton Junior Scientist Award (2005)
• AGU James B. Macelwane Medal (2011)
• Presidential Early Career Award (PECASE) (2006)
• Lamont-Doherty Mentoring Award (2017)
• NCAR Thompson Lecturer (2019)

As a principal investigator with NASA's Health and Air Quality Applied Sciences Team, Fiore collaborates with public health and air quality management groups to address emerging challenges using Earth science datasets. Her group, TEAMPACCC, specializes in analyzing large-scale models alongside diverse observational platforms.
