bsrn.physics.geometry.get_ghi_extra(times, zenith)[source]#

Calculates extraterrestrial horizontal irradiance ($GHI_E$, $E_0$). 计算地外水平辐照度 ($GHI_E$, $E_0$)。

Parameters:

  • times (pd.DatetimeIndex) – Times for calculation. 计算对应的时间。

  • zenith (numeric or Series) – Solar zenith angle ($Z$). [degrees] 太阳天顶角 ($Z$)。[度]

Returns:

ghi_extra – Extraterrestrial horizontal irradiance ($E_0$). [W/m^2] 地外水平辐照度 ($E_0$)。[瓦/平方米]

Return type:

pd.Series
