Phone: 617-494-3868

Christopher Scarpone became a member of the Environmental Measurement and Modeling Division as a student trainee in 2002. He became a full-time employee after earning his bachelor’s degree in 2003 in Electrical Engineering from the University of Massachusetts at Lowell. Scarpone has been assisting the Pipeline and Hazardous Material Safety Administration (PHMSA) reviewing firework applications for the safe transport within the U.S. since 2012. This project entails a detailed review of applications for correct construction and composition of pyrotechnic devices according the American Pyrotechnic Association (APA) Standard 87-1.

In 2011, Scarpone became a member of the Alcohol Countermeasures Laboratory, for the National Highway Transportation Safety Administration (NHTSA), which tests all Evidential Breath Testers, Alcohol Screening Devices, and Calibrating Units used by Police and transportation Agencies in the United States, and are backed up in court. The Laboratory also conducts a blood proficiency program that assists blood alcohol laboratories to conduct accurate blood alcohol measurements.

Scarpone joined a team conducting studies on wake vortex behind an aircraft in 2012 and one studying low visibility research for the Federal Aviation Administration (FAA) pertaining to landing aircraft in 2013. The main function for both projects is data collection which entails using light detection and ranging (LIDAR) or low/high resolution cameras along with high resolution weather instrumentation.

In support of the Federal Aviation Administration (FAA) and National Park Service (NPS), Scarpone has worked on developing Air Tour Management Plans (ATMP) for National Parks, expanding the Integrated Noise Model (INM) aircraft source database. These tasks included planning, training, leading the field team during data collection. Responsibilities included testing instrumentation, validating the data reduction program, data processing, computer modeling and report writing. Data processing included developing more efficient and accurate methods for analyzing ambient data collected in complex outdoor environments.

In support of the Federal Highway Administration (FHWA), Scarpone assists in the Traffic Noise Model (TNM) project. His work includes field measurements to validate TNM’s noise prediction accuracy and the analysis of data collected in the field. He also uses TNM to model sound levels in ATMP and other NPS-sponsored projects.

In addition to his work in acoustic measurement projects, Scarpone has assisted in several air quality measurement initiatives. Also, Scarpone worked on a team in support of the Department of Defense (DOD) to develop a model for contaminant dispersion in a city environment.
