README.md

check output PCA analysis SIFTER

The goal of this repository is to analyze the Principal Component's (PC's) from the PC Analysis (PCA) results from the first step of the SIFTER algorithm, where PC's are generated to simulate transmittance over the Sahara, for the TROPOMI satellite.

The script reads PCA results from an HDF5 file, extracts the principal components (EOFs), and plots them against wavelength. You can visualize different PCA modes using the plot_pca() function.

Usage

To start, navigate to the top level of the PCAanalysisSIFTER repository. Run the script from within there.

python version = 3.12. Ensure you have installed the required dependencies (h5py, matplotlib, pathlib), you can do so using the environment.yml. Run the script to inspect the PCA file structure and generate plots. Modify the plot_pca() function call to plot a certain PCA, and determine whether to save it or not.

Project Structure

The project structure distinguishes three kinds of folders: - read-only (RO): not edited by either code or researcher - human-writeable (HW): edited by the researcher only. - project-generated (PG): folders generated when running the code; these folders can be deleted or emptied and will be completely reconstituted as the project is run.
