Michael P. Jensen

Meteorologist

Dr. Jensen’s research focuses on a combination of observational and modeling studies to better understand the lifecycle of cloud systems and the role they play in the Earth’s energy balance. He has been actively involved with the Department of Energy’s Atmospheric Radiation Measurement Facility and the Atmospheric System Research Program since 1996 working on research projects studying the radiative impacts of deep convective clouds in the tropics, defining the characteristics of marine boundary layer clouds and the retrieval of cloud microphysical properties from remote sensing observations. He was the principal investigator for the Midlatitude Continental Convective Clouds Experiment (MC3E) in 2011 and will serve in the same role for the TRacking Aerosol Convection interactions Experiment (TRACER) in 2021. Recent research activities have also aimed at using radar observations and high-resolution weather modeling towards the prediction of utility outages.
