A python library to pull data and make plots from ground magnetometers. Emphasis on plots for comparing magnetometers at geomagnetic conjugate points.
To install from pypi:
pip install magplots
To install from source:
Clone git repo and run python -m pip install . from top level of directory.
Make sure that you have a folder in your directory named /output. This is where plots and dataframes will be saved.
You can check all the component functions by running the magall() function with default values.
from magplots.magFunctions import * # packaged version
# from magFunctions import * # local version
magall(is_verbose = True)
Type help('magFunctions') for function documentation.
To pull data from Tromsø Geophysical Observatory, save a password locally in a file named tgopw.txt. (You will have to obtain the password from TGO.) If no such file exists, data is automatically pulled from CDAWeb.
This plot is produced with the magplot() function:
This plot is produced with the magspect() function:
This plot is produced with the wavefig() function, which calls wavepwr() to calculate the wave power for each station within a given frequency range. By default the frequency range used is the Pc5 range, 1.667 to 6.667 mHz (150-600s). For a given timespan, the integrated wave power is plotted versus the latitude of the stations, with different colors for Arctic and Antarctic magnetometers, in order to illustrate hemispheric asymmetry. This approach is based on Figure 4 of Pilipenko 2021.
