bsrn.utils.cee_detection.gueymard_ced(ghi, ghi_extra, times=None)[source]#

Detect cloud enhancement events when GHI exceeds extraterrestrial GHI [1]. 当 GHI 大于地外水平辐照度时检测云增强事件。

Parameters:

  • ghi (array-like) – Global horizontal irradiance. [W/m^2] 水平总辐照度。[瓦/平方米]

  • ghi_extra (array-like) – Horizontal extraterrestrial irradiance. [W/m^2] 地外水平辐照度。[瓦/平方米]

  • times (array-like or pandas.DatetimeIndex, optional) – Time index for outputs. If None, a simple RangeIndex is used. 输出时间索引；若为 None，则使用 RangeIndex。

Returns:

Standardized CEE output with columns is_enhancement, cee_flag, method. 标准化 CEE 输出，包含 is_enhancement、cee_flag、method。

Return type:
