Organization: ITU-R
Publication Date: 1 September 2016
Status: inactive
Page Count: 24
scope:

This Recommendation provides methods to estimate the attenuation of atmospheric gases on terrestrial and slant paths using:

a) an estimate of gaseous attenuation computed by a summation of individual absorption lines that is valid for the frequency range 1-1 000 GHz; and

b) a simplified approximate method to estimate gaseous attenuation that is applicable in the frequency range 1-350 GHz.
