Seminar on Harmonizing the Scales of Thermometry, Radiometry, Solar Energy and Remote Sensing at NIST


Abstract
The pending redefinition of the kelvin in terms of the fixed Boltzmann constant has led to intense activity at many national measurement institutes to realize detector-based temperature scales with measurements traceable to the cryogenic radiometer or the electrical watt.  This activity has enabled harmonization of the scales for thermometry and radiometry with a common traceability route.  More importantly, this scale is also used in remote sensing calibrations of satellite sensors which are used to monitor global climate change, so that as even as these measurements improve in the future, the basis of the scale will not change.  Effort is also underway to have a common SI-traceable scale for the measurements of ground-based total solar irradiance and solar energy as well.  The work being done at National Institute of Standards and Technology (NIST), USA, in these various areas will be described. 



About the presenter
Howard Yoon is a Physicist in the Sensor Science Division at NIST.  He is the US national representative for radiation thermometry on the Consultative Committee for Thermometry at the BIPM.  He received his Ph.D. in solid-state physics from the University of Illinois at Urbana-Champaign and his BA from Swarthmore College.  He has coauthored over 100 technical publications, mostly in the areas of spectroradiometry and radiation thermometry.  He also has 2 patents in the area of spectroradiometry. He has twice won the NIST Astin award for measurement science and was also the recipient of the US Department of Commerce silver medal for scientific achievement.
