Abstract
A water vapor radiometer system based on a commercial off-the-shelf radiometer was constructed and tested as a potential alternative to the JPL advanced water vapor radiometer (AWVR). The system is simple and lends itself to installation on the antenna to allow sampling the same air mass of the antenna main beam. The system was tested in a side-by-side comparison to the AWVR. The system is capable of measuring the effect of atmospheric water vapor on the fractional frequency stability of a microwave link to 1 part in 10–14 at 1000 s. The system delivered performance within an order of magnitude of the AWVR for timescales of 100 to 10,000 s.
