Application of Two Ground-Based Microwave Radiometers for Indirect Determination of the Temperature Profile of the Atmospheric Boundary Layer
Angular measurements of brightness temperature in the frequency range between 50 GHz and 70 GHz reproduce information of the vertical temperature profile in the atmosphere. It will be measured with two radiometers. One works in the frequency range of 58 GHz and includes the lower 700 meters height (null-balancing Dicke receiver). The second works in the frequency range of 54.5 GHz (Dicke receiver using gain modulation for balancing) and includes the lower 1500 meters height. Both radiometers with their different techniques are compared to stability, noise and sensitivity. It is given a short review of two mathematical methods for determining the temperature profile out of radiation measurements.
