Dr. R. M. Hoff is a Professor of Physics at the University of Maryland, Baltimore County. He is the Science Advisor for the Joint Center for Earth Systems. Dr. Hoff has 37 years of experience in atmospheric research. His research interests are in the optical properties of aerosols and gases in the atmosphere. Dr. Hoff has been central in formulating major research programs on Raman, differential absorption, airborne and spaceborne lidar, volcanic emissions, atmospheric transport of toxic chemicals to the Great Lakes, atmospheric visibility, Arctic Haze, and dispersion of pollutants. He has led or participated in over 20 major field experiments.
He is the author of 104 journal articles and book chapters, 100 other refereed works and numerous public presentations of his work. Dr. Hoff obtained a Bachelor of Arts degree in Physics at the University of California Berkeley in 1970 and a Ph.D. in Physics from Simon Fraser University in 1975.
He has conducted research at UMBC, Environment Canada, NASA Langley Research Center, the Jet Propulsion Laboratory, and the National Oceanographic and Atmospheric Administration’s Environmental Research Laboratories.
Dr. Hoff was a member of the Science Advisory Group for the NASA Laser In-Space Technology Experiment (LITE), a space shuttle experiment. He is also a science team member on the CALIPSO spaceborne lidar. He was a member of the International Radiation Commission International Coordination Group on Laser Atmospheric Studies (ICLAS), the American Meteorological Society Committee for Laser Atmospheric Studies (CLAS) and the Stratospheric and Upper Tropospheric Aerosol focus of the International Global Aerosol Program (SUTA/IGAP/IGAC). He was Rapporteur for Long Range Transport on the WMO Executive Committee Panel of Experts/Commission of the Atmospheric Science Working Group on Environmental Pollution and Atmospheric Chemistry. He was a member of the Science Advisory Group on Aerosols to the Commission of the Atmospheric Sciences of the World Meteorological Organization. He served on a National Academy of Sciences/National Research Council Panel on Mesoscale Meteorological Observations for Multiple National Needs. He has been the Chair of the NASA Applied Sciences Advisory Group and was a member of the Earth System Science Advisory Panel for the agency. He is an external science committee member on the European Commissions ACTRIS project.
He has had committee and peer review roles at NASA, NOAA, DOE, DOD, CSA, EPA, Environment Canada, and the European Economic Community. He has held memberships in six scientific societies and served as Chairman of committees for those societies. In 2009, he became a Fellow of the American Meteorological Society and in 2012, he was awarded the NASA Distinguished Public Service Medal.
