The 60-GHz band of O2 was studied at room temperature and at low (up to 4 Torr) and atmospheric pressures. Precision measurement of central frequencies, self-broadening, and N2-broadening parameters of fine-structure transitions up to N = 27 was performed by use of a spectrometer with radio-acoustic detection (RAD). The measured parameters are compared with GEISA/ HITRAN databanks, MPM92, and other known data. An improved set of the oxygen fine-structure spectroscopic constants is obtained. The… Expand

Water Vapor Continuum Absorption in the Microwave
An evaluation of the widely used Mlawer, Tobin, Clough, Kneizys, and Davis water vapor continuum model in the microwave region, performed using measurements from ground-based radiometers operated by the Department of Energy's Atmospheric Radiation Measurement Program at sites in Oklahoma, USA, and the Black Forest, Germany.

Effect of the Oxygen Line-Parameter Modeling on Temperature and Humidity Retrievals From Ground-Based Microwave Radiometers
This paper compares the model calculations in the oxygen-band channels with the measurements collected by the ARM-operated 12-channel Microwave Radiometer Profiler, and shows that improved oxygen absorption is essential to reduce the clear-sky bias in the liquid-water path retrievals. Expand
Characterization of Atmospheric Absorption in the 60 GHz Frequency Band Using a Multi-Pole Material Model
─ Atmospheric attenuation of electromagnetic signals at the 60 GHz frequency band is dominated by oxygen absorption which represents a major obstacle to 5G communications using this band. So far,Expand
