Abstract

The stability of the main parameters of the water vapor radiometers (WVR) operating at “Quasar” network observatories for more than 3.5 years has been estimated. It is shown that the high-precision stabilization of the microwave compo-nents temperature regimes provides a way to preserve the metrological characteristics of the WVR with a significant (up to 10 %) change in the transmission coefficient of radiometric blocks over an operational interval. The calibration constant components average values remain constant if a temperature regime of the WVR components is stable. Based on the results of vertical atmospheric “cuts” (“tipcurve” calibrations), the seasonal dependence of the calibration signal on the integral water vapor content is measured.
