Abstract :
The launch of the Advanced Microwave Sounding Unit (AMSU) on the polar platforms, NOAA-K, L, M and N will provide vertical temperature and humidity soundings for inclusion in numerical weather prediction. It is important therefore, that calibration and validation of the data generated takes place. The microwave radiometers, MARSS and Deimos, onboard the Met. Offices C-130 are to be used to this end, so it is vital that their calibration be well understood. This presentation investigates the factors that can effect the calibration of airborne radiometers
