Abstract
The 20.7/31.4-GHz Water Vapor Radiometer (WVR) located on the JPL Mesa in Pasadena was used for atmospheric noise temperature measurements, Tipping curve data and on/off sun data taken on March 24, 1981 are compared. The analysis technique is described in detail. During the time of the data collection (7:00 a.m. to 12:20 p.m.), the sky was clear and the ground temperature and humidity varied from 14°C to 24°C and 65% to 51% respectively. The tipping curve data is felt to be the most accurate. The averaged results of this data for 13 measurements during this time period are: 1 atmosphere Frequency, GHz Noise temperature contribution Attenuation, dB L6.341.7 L1L16±1.2 0.18 ± 0.02 The indicated errors are lo statistical and do not represent overall measurement accuracy. Although this data is consistent with data taken previously at the Goldstone DSS 13 station, it is not necessarily representative of long-term atmospheric noise temperature average.
