Recommendation ITU-R P.835

This Recommendation provides expressions and data for reference standard atmospheres required for the calculation of gaseous attenuation on Earth-space paths.

Introduction

This recommendation provides the equations to determine the temperature, pressure and water-vapour pressure as a function of altitude, as described in the U.S. Standard Atmosphere 1976. These values should be used for calculating gaseous attenuation when more reliable local data are not available.
