  • Abstract
    We report the latest experimental determination of the water vapor continuum absorption within the atmospheric THz windows, using the long-path THz-TDS system. The continuum absorption was determined, based on the total water vapor absorption for a density of 11.2 g/m3 and the calculated Molecular Response Theory (MRT) resonant line absorption. The experimentally determined RH 0% reference signal eliminated the undesirable cross-term and thereby, increased the accuracy of the measurements.
