Python_Helpers

A library of some useful python wrappers to facilitate analysis and visualization work. Important to note here that none of these tools are directly written by myself, I've just glued the functionality into easier to digest chunks. All of the actual work is done by the wonderful people writing matplotlib and basemap

How to Install:

Please follow the instructions to get the functions working on your account.

1. clone the repository (alternatively, make a github account, fork, and clone your own version)

git clone https://github.com/AWI-Paleodyn/Python_Helpers.git

2. set up your PYTHONPATH (in .bashrc or similar)

export PYTHONPATH=${HOME}/Python_Helpers:${PYTHONPATH}

3. Test

$ ipython
... some start up message ...
[1] from plot_tools import plot_var_from_ncdf_file 

if this import successfully goes through, everything is configured correctly. Go celebrate with a coffee! ☕

How to use

I'll probably add a detailed description to this in the next several days/weeks. In principle, two important modules are ready to use:

• plot_tools : contains functions for plotting netcdf variables onto maps

• basemap_wrappers : some shortcuts for the Basemap toolkit to make maps faster

Here's a minimal example script, also included in the directory examples:

from plot_tools import plot_var_from_ncdf_file
from basemap_wrappers import map_global
import matplotlib.pyplot as plt
from scipy.io import netcdf

f = netcdf.netcdf_file("/csys/nobackup1_PALEO/pgierz/cosmos-aso/Eem120-B/post/echam5/Eem120-B_echam5_tsurf_timmean.nc")
fig, axs = plt.subplots(1, 1)
m = map_global(thisax=axs, fill_color=None)
plot_var_from_ncdf_file("tsurf", f, m)
plt.show()

Good luck! Paul
