Title :
Optimum frequency of microwave radiometry for measurements of attenuation, path relay and columnar content of water vapor

Abstract :
The attenuation and path delay due to atmospheric water vapor and its columnar content can be retrieved from only one variable measured by microwave radiometry because of their close interrelation. The optimum frequency for the measurement depends on weighting functions which mediate between them, and also on the quantity of random errors in the measurements
