Abstract :
Top-of-the-canopy infrared temperature measurements, and the mean of top-of-the-canopy and soil surface infrared temperature measurements, were equally appropriate definitions for vegetation canopy temperature when modeling the 1.4 GHz brightness of a maize canopy. The use of soil temperature as a surrogate for vegetation canopy temperature produced the largest error
