bsrn.qc.k_index.kb_kt_test(ghi, bni, bni_extra, zenith)[source]#

Check if beam transmittance ($k_b$) is less than clearness index ($k_t$) [1]. 检查直射透射率 ($k_b$) 是否小于物理上限制的晴朗指数 ($k_t$)。

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]

  • bni (numeric or Series) – Beam normal irradiance ($B_n$). [W/m^2] 法向直接辐照度 ($B_n$)。[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
