Code example for CALIPSO data

by salbloos27 » Tue Jan 30, 2024 6:43 am America/New_York

I'm trying to plot CALIPSO hdf L2 files and analyze the depolarization ratio and the color ratio and Extinction_Coefficient_532 by python, a vertical profile of the data (elevation vs the given variables each separately). for specific latitude of UAE.

is there any example code that I can use to do this?


Thank you

The file type doesn’t appear in the example page. Do you recommend any other files that could have same variables?

Have you clicked "more" link that leads to the following page?

https://hdfeos.org/zoo/LaRC_CALIPSO_py.php

It has a similar data product although the version is 4.21.

there is no helpful code for me in this section, I would like to plot the total attenuated backscatter
depolarization ratio
color ratio
similar to the quick looks in the website for a specific ___location. however, these examples only give the basemap images and the line plot of Extinction. I was wondering if I can have any help in what I need.

Thank you

I added a new CAL_LID_L2_05kmAPro-Standard-V4-51 example [1] and plot [2] on website [3].
It subsets data using UAE latitude boundary.
It plots Backscatter_Coefficient_1064.
I hope this will be enough for further processing to create plots that are similar to ones on ASDC website [4].
