    Kurt Thome obtained a BS degree in Meteorology from Texas A&M University and MS and PhD degrees in Atmospheric Sciences from the University of Arizona. He then joined what is now the College of Optical Sciences becoming full professor in 2006. He served as the Director of the Remote Sensing Group from 1997 to 2008. Thome moved to NASA's Goddard Space Flight Center in 2008 as a Physical Scientist in the Biospheric Sciences Branch.

    He was a member of the Landsat-7, ASTER, MODIS, and EO-1 Science Teams providing vicarious calibration results for those and other imaging sensors.  Thome also served on the Global Aerosol Project Team and the Landsat Calibration Team.  He served as the calibration lead for the Thermal Infrared Sensor on the Landsat Data Continuity Mission from 2009-2013.  He was the Deputy Project Scientist for CLARREO and instrument lead for the Reflective Solar Instrument and lead for the SOLARIS (Solar, Lunar for Absolute Reflectance Imaging Spectroradiometer) calibration demonstration system from 2009-2017.

    Thome was elected Fellow of SPIE in 2006 and served as the CEOS Working Group on Calibration and Validation Vice Chair from 2014 to 2016 and Chair from 2016 to 2018.

    Research Interests

    Vicarious calibration

    Relied on ground-based measurements at selected test sites including those in the desert southwest of the US to provide absolute radiometric calibration.  Thome has applied the method to over 25 imaging sensors (both airborne and spaceborne) across NASA, DoE, DoD, and commercial providers. The work included evaluating the radiometric calibration of the Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER), MODerate-resolution Imaging Spectroradiometer (MODIS), and Multiangle Imaging SpectroRadiometer (MISR) on the Terra platform, MODIS on the Aqua platform, the Advanced Land Imager (ALI) and Hyperion on Earth Observer-1 platform, and numerous commercial imaging sensors.

    Absolute radiometric calibration

    Served as the Calibration Lead for the Thermal Infrared Sensor (TIRS) on the Landsat Data Continuity Mission.  He serves as the Instrument Scientist for VIIRS and lead of the CLARREO Pathfinder Independent Calibration.
     

    Atmospheric correction

    Developed algorithms for the atmospheric correction of the solar reflective bands of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra platform

    Serving as the Atmospheric Correction Lead for CEOS’ IVOS Working Group leading to development of best practices for the atmospheric correction of imagery and for vicarious calibration.

Radiometric concepts such as projected area and solid angle, generation and propagation of radiation, absorption, reflection, transmission and scattering, and radiometric laws such as inverse square and cosine laws. The effects of optical aberrations, both chromatic and monochromatic, and methods for balancing the effects of various aberrations are described. Radiometric analysis of and impact of aberrations on imaging systems.

    Fundamentals of Remote Sensing (OPTI 450/550)- Combined Undergraduate/Graduate level course to introduce remote sensing, from the standpoint of the radiometry of optical systems; target reflectance and emission characteristics; and effects from intervening media such as the atmosphere. These tools are used to examine spectroradiometric instruments and satellite optical sensors.

    Remote sensing for the study of planet Earth (OPTI 490/590)- Combined undergraduate and graduate level course intended to provide an in-depth review of the principles, techniques, and applications of remote sensing. The course gives students an introduction to the physical basis of electromagnetic remote sensing, the concepts and practices of information extraction, and a review of a wide range of applications pertinent to earth-systems science.

    Image Processing Laboratory for Remote Sensing (ECE/OPTI 531) - Core course requirement for the Ph.D. minor program in Remote Sensing and Spatial Analysis describing techniques and applications of digital image processing in remote sensing, multispectral image enhancement and analysis, classification, feature extraction for cartography, and rule-based systems for mapping from imagery.

    Remote sensing instrumentation and techniques (ECE 583) - Course that covers measurement, instrumentation, and signal conditioning techniques required for remote sensing applications in the optical to microwave wavelength range with emphasis on atmospheric remote sensing.

    Brief Bio

    Kurt Thome obtained a BS degree in Meteorology from Texas A&M University and MS and PhD degrees in Atmospheric Sciences from the University of Arizona. He then joined what is now the College of Optical Sciences becoming full professor in 2006. He served as the Director of the Remote Sensing Group from 1997 to 2008. Thome moved to NASA's Goddard Space Flight Center in 2008 as a Physical Scientist in the Biospheric Sciences Branch.

    He was a member of the Landsat-7, ASTER, MODIS, and EO-1 Science Teams providing vicarious calibration results for those and other imaging sensors.  Thome also served on the Global Aerosol Project Team and the Landsat Calibration Team.  He served as the calibration lead for the Thermal Infrared Sensor on the Landsat Data Continuity Mission from 2009-2013.  He was the Deputy Project Scientist for CLARREO and instrument lead for the Reflective Solar Instrument and lead for the SOLARIS (Solar, Lunar for Absolute Reflectance Imaging Spectroradiometer) calibration demonstration system from 2009-2017.

    Thome was elected Fellow of SPIE in 2006 and served as the CEOS Working Group on Calibration and Validation Vice Chair from 2014 to 2016 and Chair from 2016 to 2018.
