Health warning

Note that the data quality varies from October 2019 onward due to the orbit changes of Swarm A & C:

• Remove 2021/07/01 to 2022/01/13
• Change polar exclusion zone for 2019/10/01 to 2021/06/30 and for 2022/01/14 onward:
• exclude where abs(latitudinal crossing point) + 6deg < 90deg

These changes are yet to be made in the data products as of writing (April 2022)

(this has a simpler temporary environment, but won't work with the notebooks under "Geomagnetic Data & Models")

Sorry I didn't update this! Here it is: https://raw.githubusercontent.com/MagneticEarth/IAGA_SummerSchool2019/master/data/external/oamjumpsapplied.dat

Probably just remove this section and create a dedicated page that goes into it

Only using one component to keep it simpler. The radial component is the least contaminated so damping is less important

NB: The source (CDF) files provide the measurements in the RTP coordinates rather than NEC. In VirES, we provide them in NEC coordinates for consistency with other Swarm products.

This has led to the misleading variable descriptions in data retrieved from VirES, stating that they are given in "spherical polar (r,theta,phi) vector components [i.e (-C,-N,E) components in NEC frame]". We have not fixed this yet

is there a nice library for accessing these? are they published data?

will be able to replace with data loading live from vires

can investigate hiding code to make the book more friendly to browse https://jupyterbook.org/interactive/hiding.html

I'll have a look for simple "date/time" input boxes through ipywidgets or similar

Change to e.g. "IAGA and friends" This is displayed identically on all pages. Perhaps we can add an "authors" element to each notebook (at top or bottom)
