DESCRIPTION:Arlene Fiore (Peter H. Stone and Paola Malanotte Stone Professo
 r of Earth\, Atmospheric and Planetary Sciences at MIT)\n\nObserved trends 
 in tropospheric ozone and hydroxyl radical (OH) are shaped by the combined 
 influence of changing climate and air pollutant emissions\, as well as natu
 rally arising climate variability. I will show how we are using initial-con
 dition ensembles with a fully coupled chemistry-climate model to quantify t
 rends in upper tropospheric ozone arising from anthropogenic influence and 
 identify when and where anthropogenic signals are most detectable. I will a
 lso share highlights from an idealized chemistry-climate model that offers 
 insights into the pathways controlling how tropospheric OH responds to surf
 ace warming. \n\n \n\nArlene Fiore joined the EAPS faculty in 2021 as the P
 eter H. Stone and Paola Malanotte Stone Professor of Earth\, Atmospheric an
 d Planetary Sciences. She attended Harvard University\, earning an AB in en
 vironmental geoscience in 1997 and completing her PhD studies in Earth and 
 planetary sciences in 2003. Fiore spent seven years as a research scientist
  in the NOAA Geophysical Fluid Dynamics Laboratory before being appointed t
 o the faculty at Columbia University’s Department of Earth and Environmenta
 l Sciences and Lamont-Doherty Earth Observatory in 2011.\n\nFiore has a lon
 g history of professional service\, including serving on the National Acade
 my of Sciences Board on Atmospheric Sciences and Climate\, multiple NCAR (N
 ational Center for Atmospheric Research) advisory panels and committees\, a
 nd has authored or co-authored numerous reports on issues of air quality an
 d climate for policymakers and government agencies. As a principal investig
 ator and member of the NASA Health and Air Quality Applied Sciences Team\, 
 she partners with air and health management groups to address emerging need
 s with applications of satellite and other Earth science datasets. Among ot
 her honors\, Fiore has been recognized by the American Geophysical Union wi
 th the James R. Holton Junior Scientist Award in 2005 and the James B. Mace
 lwane Medal in 2011.
