# How to use this dataset¶

This document is kept under version control in a git repository. The repository is hosted on GitHub (and the documentation made with GitHub Pages). The repository is https://github.com/oldweather/20CRv3-diagnostics. This repository contains everything you need to reproduce or extend this work, but note that the 20CRv3 data is still preliminary, and access to it is currently restricted.

If you are just looking to extract 20CRv3 data as netCDF files from the tape archive at NERSC then you don’t need to install this software - you can use the version already installed on Cori:

If you want to do anything else, you will need to install your own version of this package:

If you are familiar with GitHub, you already know what to do: If you’d prefer not to bother with that, you can download the whole dataset as a zip file.

To re-run the scripts included, first install three packages this depends on:

python setup.py install --user
