摘要
The integration methods along the chord pointed from source to receiver, which wasproposed by Moritz (1967), are developed for various observation scenario. According todifferent accuracy requirements the mapping function is represented as a main term plus cor rection terms. An asymmetric atmospheric distribution is taken into account by means of ahorizontal gradient compensation- The suggested procedures are expected to offer a high ac curacy for the elevation angle down to below 10 degrees, and might be conveniently usedboth in modeling and in calculating the neutral atmospheric delays for different atmosphericprofiles.
