Experimental estimates of the value and temperature dependence of the air-humidity quadratic component of the atmospheric water-vapor absorption coefficient in the frequency band of 140?410 GHz

A review of sources of systematic errors and uncertainties in observations and simulations at 183 GHz

“…Self-broadened (pure water vapor or quadratic with humidity) and foreign-broadened (mixture with air or linear with humidity) continuum coefficients C (in (dB km −1 )/(GHz kPa) 2 ), as in Rosenkranz (1998Rosenkranz ( , 1999. Symbols are field and laboratory data (filled blue diamonds are from Kuhn et al, 2002; open blue diamonds are from Godon et al, 1992and Bauer et al, 1993 green open circles are from Katkov et al, 1995; red squares are from Liebe, 1984 andLayton, 1987; black dots are from Koshelev et al, 2011; pink triangles are from Becker and Autler, 1946). Statistical uncertainty of individual points in each series is approximately equal to or less than the size of the points.…”

On the nature of sub-THz continuum absorption in CO2 gas, its mixture with Ar, and in pure water vapor

“…70–73 When considered conjointly with the previous results from ref. 47 and 74–82, these data reveal a sharp decrease in the spectral function of the H 2 O–H 2 O continuum in the 500–1000 GHz range (Fig. 9).…”

“…The two variable parameters of the model are determined from the best fit to the experimental spectra. 47,70,73–82 These experimental data and the simulation results are presented in Fig. 9.…”
