Dr. Mark Green has over 30 years experience in the fields of air pollution and meteorology.  Dr. Green holds the position of Research Professor in DRI’s Division of Atmospheric Sciences. His research has concentrated on determining the causes of haze in both remote and urban areas and in characterization and source attribution of atmospheric aerosols.  He was DRI’s Principal Investigator for numerous current and past visibility related studies, including the Las Vegas Valley upper air measurement study, Project MOHAVE and BRAVO regional visibility studies, the Columbia River Gorge Air Quality and Visibility Study, the Las Vegas Valley Visibility and PM2.5 Study, the CENRAP Scoping Study, the CENRAP monitoring umbrella contract, the Las Vegas Valley Carbon Source Apportionment Study, the Western Regional Air Partnership Causes of Haze Study, and the Lake Tahoe Visibility Impairment Source Apportionment Study.  Dr. Green served as a member of the Meteorology Subcommittee, Grand Canyon Visibility Transport Commission (GCVTC), providing substantial portions of the subcommittees' analyses and reports. He has also contributed to EPA guidance documents for PM2.5 monitoring.  As a result of his leadership on these projects, Dr. Green is a nationally recognized expert in visibility assessment.  Recent work has included evaluation of organic carbon artifact for the EPA Chemical Speciation network and IMPROVE network.  Dr. Green has also served as expert witness for regional haze issues and accidents related to extreme weather conditions.
