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… 

Air-Broadened Half-Widths of the 22- and 183-GHz Water-Vapor Lines

Air-broadened half-widths of the 22- and 183-GHz water-vapor lines and associated uncertainties have been determined using comparisons between ground-based radiometric measurements from Atmospheric

Modern Resonator Spectroscopy at Submillimeter Wavelengths

Classical resonator spectroscopy methods have been realized for the first time in the submillimeter wave range. A resonator spectrometer was developed earlier at the IAP RAS on the basis of an open

Uncertainty of atmospheric microwave absorption model: impact on ground-based radiometer simulations and retrievals

Abstract. This paper presents a general approach to quantify absorption model uncertainty due to uncertainty in the underlying spectroscopic parameters. The approach is applied to a widely used

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.

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,

Observations of stratospheric and mesospheric O3 with a millimeter-wave radiometer at Rikubetsu, Japan

Abstract We have been measuring brightness temperature spectra of the atmospheric ozone (O3) emission at 110.83 GHz with a millimeter-wave radiometer (MWR) located at Rikubetsu, Japan, since November

Long-Term Observations of Microwave Brightness Temperatures over a Metropolitan Area: Comparison of Radiometric Data and Spectra Simulated with the Use of Radiosonde Measurements

The difference between observed and simulated microwave spectra obtained from more than four years of microwave and radiosonde observations over Nizhny Novgorod are analyzed, finding a systematic bias in zenith-measurements and a dependence on the elevation angle and absorption model.

Improving the Modeling of Oxygen-Band Absorption: A Model-Measurement Comparison

The Atmospheric Radiation Measurement (ARM) program maintains a suite of instruments in various locations to provide continuous monitoring of atmospheric parameters. Temperature and humidity
