ppcpy.cloudmask.cloudscreen.cloudScreen_MSG(height, RCS, slope_thres, search_region)[source]#

CLOUDSCREEN_MSG cloud screen with maximum signal gradient.

INPUTS:

height: array: Height in meters.
signal: array (time, height) !! this is transposed compared to the original implementation: Photon count rate in MHz.
slope_thres: float: Threshold of the slope to determine whether there is strong backscatter signal. [MHz*m]
search_region: list or array (2 elements): [baseHeight, topHeight] in meters.

OUTPUTS:

flagCloudFree: boolean array: Indicates whether the profile is cloud free.
layerStatus: matrix (height x time): Layer status for each bin (0: unknown, 1: cloud, 2: aerosol).
