Mark Gunzelman, an AMS Member, is a Senior System Analyst for Aviation Meteorological Applications, Inc. in Reston, Virginia. Since 2008 he has been supporting the Federal Aviation Administration to upgrade and improve the air industry of the future known as the Next Generation Air Transportation System. His support involves mitigating the atmospheric and space weather (SWx) hazards and their impacts on aviation operations. Mr. Gunzelman's current effort is focused on SWx impacts on transcontinental flights, especially over the polar region, affecting communication, navigation, and elevated radiation level exposure. He recently drafted the first-ever Concept of Operations document for the International Civil Aviation Organization, encapsulating a set of requirements. The goal is for this document to serve as a roadmap to globally harmonize space weather information for products and services in a single standard. From 2006-2008, Mr. Gunzelman was a Senior Staff Scientist for the Science and Technology Corporation at the Office of the Federal Coordinator for Meteorology. He was the Executive Secretary for the National Space Weather Program Council and the Committee for Space Weather. Commander Gunzelman retired from the United States Navy in 2006 with over 26 years of military service, including several ship tours. He has substantial staff/project-level and technical management experience that included over six years in the specialized space weather arena. His breadth of military expertise involves meteorology, oceanography, geospatial information and services, and precise time, time interval and astrometry programs. Mr. Gunzelman's tour of duty as the Deputy Superintendent of the U.S. Naval Observatory Facility in Washington, D.C. was to manage over 50 Hydrogen and Cesium clocks as the nation's official time keeper. Precision time is maintained at less than one-billionth of a second (the time it takes light to travel one foot), which is crucial for precision inter-continental military operations, the US space program, and commercial transactions including those on Wall Street. His duties included managing these clocks through the uncertainties of the Y2K scare. Mr. Gunzelman has a BS degree in meteorology from Florida State University and an MS degree in meteorology and physical oceanography from the Naval Postgraduate School.
