Screening the CALIPSO aerosol profiles based on CAD score

Hello, I am trying to screen the extinction coefficient profiles from CALIPSO data (CAL_LID_L2_05kmAPro-Standard-V4) based on CAD score (CAD score>-20) and plot it vs altitude (https://hdfeos.org/zoo/MORE/LaRC/CALIPSO/CAL_LID_L2_05kmAPro-Standard-V4-21.2021-01-10T21-34-11ZN.hdf.py.png).

Re: Plotting CALIPSO aerosol feature subtype using CALIPSO Aerosol Layer data

Thankyou for your response, but I am trying to plot CALIPSO vertical feature mask data in two ways (attached sample images). First i want the contour plots and next i want the frequency of occurrences of each feature subtype (2nd image shows the frequency of occurrence of dust feature subtype).

Plotting CALIPSO aerosol feature subtype using CALIPSO Aerosol Layer data

I am trying to plot the frequency of occurrences of aerosol feature subtype using the CALIPSO Vertical feature mask data (CAL_LID_L2_VFM-Standard-V4-51). I am able to plot the contours of the feature subtypes using https://hdfeos.org/zoo/LaRC_CALIPSO_py.php. Since my area and time period of study is...

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

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.

Re: Plotting CALIPSO using Python

Hello,
Thank You for helping me out. As mentioned earlier I wanted to plot backscatter coeff vs altitude for a specific range of latitude, not a contour plot. But, my problem is solved now. I got an idea of how to subset the latitude from the code.

Thank You once again!

Re: Plotting CALIPSO using Python

Thank you for your response. I have already taken subsetted data using the ASDC's CALIPSO Subsetter. But, now I have to further subset it based on different latitude ranges like 10-20N, 20-30N etc. So, how to modify the https://hdfeos.org/zoo/MORE/LaRC/CALIPSO/CAL_LID_L2_05kmAPro-Standard-V4-21.2021...

Plotting CALIPSO using Python

Hello everyone, I'm trying to plot CALIPSO hdf L2 files and analyze the Backscattering coefficient from them, and to do this I want to plot (via Python) a vertical profile of the data (elevation vs Backscattering coefficient). I found an example from the Comprehensive Examples site below: https://hd...

Plotting CALIPSO using R Studio

How to read CALIPSO level 3 HDF4 file and plot it in R? I have downloaded the CALIPSO Level 3 data and want to plot the subdataset- Total_Backscatter_Coefficient_532. Any help in this regard will be highly appreciated.
