Atmospheric Tomography Experiment (ATom)

Lead PI: Arlene H. Fiore

Unit Affiliation: Ocean and Climate Physics, Lamont-Doherty Earth Observatory (LDEO)

April 2015 - March 2021
Global ; Remote Atmosphere
Project Type: Research

DESCRIPTION: We are contributing model simulations being used to assess inter-model differences in atmospheric oxidation, and the potential to constrain these differences with new measurements taken from the four ATom flight campaigns
