Matthew Christensen

Global Atmospheric Modeling
Earth Scientist


I received my PhD in Atmospheric Science from Colorado State University in 2012. I have worked at JPL, RAL (UK), and University of Oxford (UK). My research focuses on aerosols on clouds, precipitation and effective radiative forcing using models of different scales and multi-sensor satellite observations.
