A Paradigm Shift in the Application of Thermal Infrared Remote Sensing for Land Surface Modeling: John Norman's Critical Contributions Academic Article uri icon


  • Over 10 years ago, John Norman and co-authors proposed a thermal-based land surface modeling strategy that treated the energy exchange and kinetic temperatures of the soil and vegetated components in a unique “two-source” approach addressing the key factors affecting the convective and radiative exchange between the soil-canopy system and the lower atmosphere. While the model is fairly simple, requiring surface information operationally available from remote sensing, it is physically robust requiring no a priori calibration that has plagued many previous approaches. This modeling strategy also accommodates in a relatively simple way the influence of soil background temperature and energy exchange as well as radiometer viewing angle on the thermal signal. John Norman's contribution came at a time when thermal-based techniques for large scale land surface …
