Weather and Climate Variability Graphics

Repository contains all of the scripts used in making the figures within (https://zacklabe.com/arctic-sea-ice-figures/). Scripts are not intended to be the most efficient or simplest method of plotting and reading data. However, they work for their current purpose. Check back soon for new scripts and/or comments!

Description

• bin/: Shell scripts
• Data/: Additional data files not provided by Python URL functions
• Examples/: Arbitrary figures as examples from listed scripts
• Figures/: Output directory for figures produced by the scripts (intentionally empty)
• Scripts/: Main Python scripts/functions used in data analysis and plotting. More details are provided in explainScripts.txt for each script and function.
• Dockerfile: Docker image manifest for building dependencies
• requirements.txt: List of environments and modules associated with the most recent version of this project. A Python Anaconda3 Distribution was used for the analysis. Tools including NCL 6.4.0, CDO, and NCO were also used for initial data manipulation. ImageMagick is used for most of the animations (GIF). All code has been tested with Python 3.6.

Docker

Build image

Build an image containing all the dependencies by running bin/build_image.sh. Takes optional VERSION environment variable, defaults to 'latest'. Designed to be used with a volume mount to the repository root so that scripts can be modified without rebuilding the image.

Run scripts in container

Once the image has been built run bin/run_container.sh <script path>. Also takes optional VERSION environment variable, defaults to 'latest'. Figures will be written to the local Figures directory.

Example: bin/run_container.sh Scripts/Temperature/plot_ArcticTemperatures_Reanalysis.py
