Compute the Oxygen and Water Vapour as described in ITU-R P.676-9 document (International Telecommunication Union) https://www.itu.int/dms_pubrec/itu-r/rec/p/R-REC-P.676-9-201202-S!!PDF-E.pdf

Installation

npm install attenuationbyatmosphericgases

Usage

var GetAirAttenuation = require('attenuationbyatmosphericgases').GetAirAttenuation;
var GetWaterAttenuation = require('attenuationbyatmosphericgases').GetWaterAttenuation;
let freq = 60; // 60 GHz
let temperature = 20; // 20 degree
let pressure = 1000; // hpa
console.log(GetAirAttenuation(freq, temperature, pressure));
console.log(GetWaterAttenuation(10, 15, 1013, 7.5));
