This routine computes an approximation to the one-way attenuation expected given microwave frequency, pressure, temperature, vapor pressure, cloud and rain amount
- Parameters
-
freq [in] Frequency, in Hz (2-15 GHz, 34-36 GHz, 93-95 GHz) atm_pres [in] Atmospheric pressure (dry + wet), in Pa (10,000-110,000 Pa) temp_air [in] Temperature of the air, in K (180-330 K) temp_hydro [in] Temperature of the hydrometeors (cloud, rain, snow), in K (180-330 K) e_in [in] Water vapor pressure, in Pa w_in [in] Cloud liquid water content (g/m3) r_in [in] Rain rate (mm/hr) s_in [in] Snow rate (mm/hr) atten_total [out] -1 when well outside of the parameter space for which it was designed, or the expected one-way attenuation in dB/km
