The meaning of ZENITH DISTANCE is the angular distance of a celestial object from the zenith measured by the arc of a vertical circle intercepted between the object and the zenith : the complement of the altitude.

The zenith angle is defined by (8-61)cosZ=cosϕ cosδsuncoshr+sin δsunsinϕ,where ϕ is latitude, δsun is the declination of the sun (which ranges between +23.5° on 21 June to –23.5° on 22 December),20 and hr is the hour angle (0° ≡ noon). ...
3.Based on the atmospheric transmission model,through the actual ray track,thezenith angleis revised,which is a complicated function with launch angle and altitude.基于大气传输模型,采用光线传输的实际轨迹对天顶角进行修正处理,得出天顶角随发射角和传输高度的变化复杂函数。 4)Large zenith angle大天顶角 5...
I would also propose to change the wording from "altitude" to "zenith"

In a scientific context, the zenith is the direction of reference for measuring the zenith angle (or zenith angular distance), the angle between a direction of interest (e.g. a star) and the local zenith - that is, the complement of the altitude angle. ...
thealtazimuth coordinate system; its altitude above the celestial horizon is 90°. The angular distance from the zenith to a celestial body is called the zenith distance. The nadir, directly opposite the zenith, has a zenith distance of 180°; the celestial horizon has a zenith distance of ...
