Atmosphere continuum absorption investigation at MM waves

The water-related continuum broadband measurement by the resonator spectrometer reveals strong influence of water adsorbing on resonator elements on results of the continuum parameters measurements. Analysis of the MM/SubMM continuum measurement methods used in the earlier studies leads to the conclusion that water adsorbing onto mirrors is a common factor influencing the water-related continuum parameters obtained in all well-known laboratory experiments. The paper presents the results of water-related continuum measurements at MM waves.
