Removing clouds from Extinction Coefficient data from CALIPSO and plot it in Python

Hello,
I'm trying to plot Extinction_Coefficient_532 vs altitude from CALIPSO data, via Python. I tried using the comprehensive example
https://www.hdfeos.org/zoo/MORE/LaRC/CALIPSO/CAL_LID_L2_05kmAPro-Standard-V4-21.2021-01-10T21-34-11ZN.hdf.py
But, I want to mask the extinction coefficient values containing clouds and then plot it. How to do it can someone help me out?

Hello,
I want to be sure of what you are asking. Are you looking to plot something like the figure below? This is the vertical cross section (curtain) of the extinction coefficient values.

I need something like this kind of plot (attached image file). I am able to plot this but the problem is I need to remove the cloud extinction coefficient values from the total extinction coefficient values as I need to plot the aerosol extinction coefficient only.

Hello,
Since you are using the collection CAL_LID_L2_05kmAPro-Standard-V4-21 (CALIPSO Lidar Level 2 Aerosol Profile) to plot the Extinction_Coeffiecent_532 variable, you will not have to worry about any cloud extinction coefficient values. If you want to plot any cloud extinction coefficient values, use the collection CAL_LID_L2_05kmCPro-Standard-V4-21 (CALIPSO Lidar Level 2 Cloud Profile).
