1. The relationship between brightness temperature and temperature can be written as: 2. The brightness temperature is not a temperature as ordinarily understood. 3. The fraction of brightness temperature to actual temperature is defined as the emissivity. 4. Nonthermal sources can have very high brightness temperatures . 5. Venus has a high brightness temperature in the radio frequencies compared to the infrared. 6. For ideal black bodies, the brightness temperature is also the directly measurable temperature. 7. The Hydro-Estimator algorithm differs from the original AE by using a brightness temperature screening technique. 8. This implies a greater sensitivity to salinity in the vertical component of brightness temperature than in the horizontal. 9. Where T _ b refers to the brightness temperature and T is simply the temperature of the surface seawater. 10. The vertical component of the brightness temperature shows a greater spread in constant salinity curves than the horizontal component.
