Michael P. Jensen

Meteorologist

Dr. Jensen’s research focuses on the use of both satellite and ground-based remote sensing observations in order 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 Program since 1995 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 lead investigator for the Midlatitude Continental Convective Clouds Experiment (MC3E) in 2011. Dr. Jensen is also the Science Translator for the ARM Cloud Lifecycle Working Group overseeing the development of cloud related value-added data products from ARM observations.
