bsrn.qc.k_index.kb_limit_test(bni, bni_extra, elevation, ghi)[source]#

Check if beam transmittance ($k_b$) stays within absolute physical limits based on elevation [1].

Parameters:

  • bni (numeric or Series) – Beam normal irradiance ($B_n$). [W/m^2]

  • bni_extra (numeric or Series) – Extraterrestrial beam normal irradiance ($E_{0n}$). [W/m^2]

  • elevation (numeric) – Site elevation. [m]

  • ghi (numeric or Series) – Global horizontal irradiance ($G_h$). [W/m^2]

Returns:

flags – Boolean flags (True = Pass). [bool]

Return type:

Series or ndarray
