ABSTRACT:
The system is essentially an arrangement for determining the amount of liquid water in the atmosphere by monitoring the microwave signals received within a single frequency band around 31.65 GHz. The system has improved reliabililty since it is relatively simple employing existing technologies. It is generally a process and an arrangement wherein microwave signals naturally occurring in the atmosphere are detected by a receiver which is tuned to a relatively narrow band around the 31.65 GHz range. The converted signals from the microwave monitoring system are available for strip chart recording or for display directly or after introduction to a computer where they are processed by taking into account the known oxygen content of the atmosphere under monitor and the approximation of the vapor content. By recognizing these factors along with the cosmic radiation present, an output signal which is a close approximation of the actual liquid water content in the atmosphere is produced as a usable output signal for any utility device.
