Paper Abstract

A practical, PC-operated atmospheric propagation model (MPM) was developed by ITS that predicts attenuation (dB/km) and delay (ps/km) rates for frequencies between 1 GHz and 1 THz. Input variables are barometric pressure, ambient temperature, relative humidity, hygroscopic aerosol concentration, suspended water or ice droplet concentration, and rain rate. Details of the MPM code are discussed briefly, model predictions are presented, and comparisons with data from propagation experiments studying water vapor and fog effects (50 to 430 GHz) are shown.
