Abstract

In order to obtain the variation rule of shadow length of the pole in a certain period of time, this paper establishes a model of the change of shadow length with each parameter. First of all, according to the observation date, the solar declination is obtained. In this paper, to make the calculation simplified, several items that have little effect on the results of the solar declination are ignored, and the simplified formula for calculating the solar declination can be obtained. Second, using the relationship between a series of sun angles, the solar elevation angle is expressed as a function of the observation time.
