Abstract :
A third-generation S-band radiometer has been calibrated at intervals over 3-1/2 years. The built-in stabilization concepts have proven to be very effective. In spite of some nonideal conditions (on runway, in wind, and in rain), an rms value of 0.7 K calibration repeatability has been observed with an average temperature deviation (bias error) of 0.03 K.
