    1. ds.plot.scatter(x="Timestamp", y="Vixv", ax=axes[0], s=0.1) ds.plot.scatter(x="Timestamp", y="Vixh", ax=axes[1], s=0.1) ds.plot.scatter(x="Timestamp", y="Viy", ax=axes[2], s=0.1) ds.plot.scatter(x="Timestamp", y="Viz", ax=axes[3], s=0.1, label="Velocities")

      Change to:

      ds.plot.scatter(x="Timestamp", y="Vixv", ax=axes[0], s=1, linewidths=0) ds.plot.scatter(x="Timestamp", y="Vixh", ax=axes[1], s=1, linewidths=0) ds.plot.scatter(x="Timestamp", y="Viy", ax=axes[2], s=1, linewidths=0) ds.plot.scatter(x="Timestamp", y="Viz", ax=axes[3], s=1, linewidths=0, label="Velocities")

    1. Abstract: Access to the field aligned currents evaluated by the dual satellite method (level 2 product). We also show an orbit-by-orbit plot using a periodic axis to display (centred over both poles) an overview of the FAC estimates over two weeks.

      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)

    1. Geomagnetic pulsations¶ .. see https://iaga-school-2019.netlify.app/notebooks/1-visualising-geomagnetic-observatory-data#geomagnetic-pulsations Hartland (HAD) second data are not available. Fetching CLF instead:

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

    1. # Using only the radial component, perform the inversion: G = G_radius d = B_radius m = np.linalg.inv(G.T @ G) @ (G.T @ d)

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

    1. Estimated core GVO magnetic field, spherical polar (r,theta,phi) vector components [i.e (-C,-N,E) components in NEC frame]

      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

      will be able to replace with data loading live from vires

    2. By David Kerridge et al.

      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)

    1. prototype quicklook routine

      The intention is that in the future we will be able to access such routine from something like:

      from viresclient import SwarmQuicklooks
      fig = SwarmQuicklooks.AEJxLPS.plot()
