Submillimeter Wave High Resolution Atmospheric Transmission Measurements Study

摘要

The measurement of atmospheric transmission under various weather conditions at submillimeter wavelengths was carried out using an interferometer modulator transmitter and cooled composite bolometer receiver over transmission paths to 100 meters. Measurements were made in the laboratory and outside, with relative humidity to 97%. Spectral resolution was better than 0.1 centimeters to -1 power, and spectral range extended from 100 microns to just beyond 1.0 millimeter. Although some channeling was observed in earlier spectra, this effect was removed in later measurements, and data quality is generally excellent. (Author)
