bsrn.qc.diff_ratio.k_kt_combined_test(ghi, dhi, bni_extra, zenith)[source]#

Combined check of diffuse fraction ($k$) and clearness index ($k_t$) [1]. 结合散射分数 ($k$) 和晴朗指数 ($k_t$) 的测试。

Parameters:

  • ghi (numeric or Series) – Global horizontal irradiance ($G_h$). [W/m^2] 水平总辐照度 ($G_h$)。[瓦/平方米]

  • dhi (numeric or Series) – Diffuse horizontal irradiance ($D_h$). [W/m^2] 水平散射辐照度 ($D_h$)。[瓦/平方米]

  • bni_extra (numeric or Series) – Extraterrestrial beam normal irradiance ($E_{0n}$). [W/m^2] 地外法向辐照度 ($E_{0n}$)。[瓦/平方米]

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

Returns:

flags – Boolean flags (True = Pass). [bool] 布尔标记（True = 通过）。[布尔值]

Return type:

Series or ndarray
