Research Interests

Dr. Marchand's research focuses on improving the representation of clouds in climate and cloud resolving models.  In recent years, he has developed and applied MISR and CloudSat instrument simulators (which are part of the Cloud Feedback ModelIntercomparison Project (CFMIP) Observations Simulator Package, COSP) to the study of the Multiscale Modeling Framework climate model and its associated cloud-resolving model (the System for Atmospheric Modeling).  More broadly, his research includes developing cloud property retrievals based on satellites and ground-based systems, as well as validating retrievals using airborne in situ observations.  Dr. Marchand has participated in many field campaigns including FIRE-ACE, CRYSTAL-FACE, ARM-2000, M-PACE and most recently StormVEx.  He is a member of the NASA CloudSat and MISR instrument teams and a long time participant in the U.S. Department of Energy Atmospheric System Research program, as well as a participant in the Center for Multiscale Modeling of Atmospheric Processes (CMMAP).  Dr. Marchand earned his Ph.D in electrical engineering from Virginia Tech in 1997 and since that time has held research positions at Penn State University, the U.S. Department of Energy Pacific Northwest National Laboratory, and the University of Washington Joint Institute for the Study of the Atmosphere and Ocean.
