SERIES EXPANSION OF ASTRONOMICAL ATMOSPHERIC REFRACTION
天文大气折射的级数展开式

The correction of Astronomical Atmospheric Refraction(AAR) is one of the important topics in astronomy and geodesy.On the basis of the literature 1 and 2,series expansion theory of AAR was restudied,a new series expansion was provided.The new expansion can expanded to the arbitrary order and times items,and reached the sub-milli-arc-second theoretical accuracy.In addition,the phase atmospheric refractive index near the ground had been extracted from the expansion,as a single unknown parameter,so,new expansi...
