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 the TRacking Aerosol Convection interactions Experiment (TRACER) in 2021-2022. Additional recent research activities have also aimed at using radar observations and high-resolution weather modeling towards the prediction of utility outages.

    September 15, 2021

    The TRacking Aerosol Convection interactions ExpeRiment (TRACER) is scheduled from October 2021 through September 2022 in and around Houston, Texas. TRACER’s main objective is to provide convective cloud observations with high space and time resolution over a broad range of environmental and aerosol conditions. These observations will help to constrain high-resolution numerical model simulations, advance fundamental process-level understanding of convective motions and microphysics, and improve the representation of deep convection in earth system models. Learn more about the TRACER campaign at https://arm.gov/research/campaigns/amf2021tracer.
