Dr. Whetstone is recognized for his outstanding leadership of the NIST Greenhouse Gas (GHG) Measurements Program, and development of Urban Testbeds in Indianapolis, Los Angeles Megacity, and the Northeast Corridor of the U.S. to document GHG emissions in urban environments, which account for more than 70% of global GHG emissions. He has led research programs to improve the accuracy of GHG measurements in the atmosphere and the reliability and credibility of GHG emission measurements, and led international efforts to expand such programs globally and document the impact of mitigation efforts.
