I am trying to make a CALIPSO CALIOP 532 nm Extinction Coefficient Plot from an hdf4 file that looks like this: https://hdfeos.org/zoo/MORE/LaRC/CALIPSO/CAL_LID_L2_05kmAPro-Standard-V4-21.2021-01-10T21-34-11ZN.hdf.py.png

I am attempting to use this sample python script: https://hdfeos.org/zoo/MORE/LaRC/CALIPSO/CAL_LID_L2_05kmAPro-Standard-V4-21.2021-01-10T21-34-11ZN.hdf.py

I used miniconda to create an environment where I loaded in matplotlib, numpy, and pyhdf libraries. I then ran this script in VSCode Python version 3.12.3 and ran into some issues with the libraries (I've included a screenshot of the errors I received). I was wondering if anybody has seen this issue before and knows how to troubleshoot.

Otherwise, what is another way to create an extinction coefficient plot?

Dear Sidneyhipp,

Thank you for contacting us.

Hello @sidneyhipp

Thank you for your interest in CALIPSO data.

I used Anaconda instead of Miniconda and successfully plotted the graph with the code you provided.

If you are interested in using Anaconda you can download it here.

Once you have it, there are a few options to create your conda envrionment:

1. Create a YAML file.
What the YAML file will consists of:

name: CALIPSO_env
channels:
- conda-forge
dependencies:
- numpy=2.0.0
- matplotlib=3.8.4
- pyhdf=0.11.4

Then run the following command: conda env create -f environment.yml


2. Create environment with commands

To create environment run the command: conda create -n CALIPSO_env

Then install the following libraries:
conda install conda-forge::numpy
conda install conda-forge::matplotlib
conda install conda-forge::pyhdf

I do not have Miniconda installed on my computer and if you wish to continue using it, you can contact the HDF-EOS Tools and Information Center, they're the ones that created the code:
eoshelp@hdfgroup.org

Please let us know if you have any questions.

Regards,
