Atmospheric Attenuation of Millimeter and Submillimeter Waves: Models and Computer Code

Abstract

Atmospheric attenuation of millimeter and submillimeter waves is calculated for clear, fog, cloud and rain atmospheres. The frequency range considered is 1-1000 GHz. The clear atmospheres transmission spectra is calculated by a computer efficient algorithm of AFGL's HITRAN code. This new code is called FASCODE-1. The hydrometeor attenuation of fog, clouds and rain (precipitation), calculated by Mie scattering is addend to FASCODE-1. Models of fog, clouds and rain typical of mid-latitude temperate regions are used in calculations of transmission and attenuation.
