摘要：

Over 5000 absolute absorption values for pressure-broadened 02 lines in dry air were measured at frequencies from 49 to 67 GHz in 0. 1-GHz-increments. The controlled laboratory studies were carried out at three temperatures (6, 30, and 54-degrees-C) for 11 pressure values ranging between 1.3 and 101 kPa. The spectrometer consisted of a Fabry-Perot resonator combined with an automatic network analyzer. The detection sensitivity was better than +/-0.02 dB/km, and measurement uncertainties were estimated to be typically better than +/-0.05 dB/km for attenuation rates below 3 dB/km, or better than +/-2% for higher rates. The extensive data set was compared with predictions by an established model (MPM89). Systematic discrepancies were recognized and reduced by means of a readjustment of line parameters. The new model (MPM92) is given here.
