Simple forest canopy thermal-exitance model

The authors describe a simple model to calculate brightness temperature and surface-energy balance for a forest-canopy system. The root mean-square (RMS) error in brightness temperature was 2.5/spl deg/C. The corresponding RMS errors for net radiation, latent, and sensible heat were 38.9, 30.7, and 41.1 W m/sup -2/ respectively.
