The download contains software developed by NTIA. The MPM software is available for download as a "zip" file. It is necessary to include the following spectroscopic line coefficient data files in the working directory: oxygen.dat and water.dat. Hans Liebe's final publication. MPM Software (which operates in a DOS environment) that aligns with this publication is available in three different versions, which compute frequency, humidity, and pressure profiles. This criteria also defines whether water droplets or ice particles contribute to attenuation and delay. In the temperature range -40 <= T <= 0 C, the user specifies Es over liquid water or ice. The input data includes the frequency (F), pressure (P), temperature (T), relative humidity (RH), and rain rate (RR). The output is expressed in real and imaginary parts of N, or in specific rates of power attenuation and propagation delay.
