Visualizing Network Health

The lightning Network Health product displays a grid of cells and provides a visual indication as to whether the lightning network has a sufficient detection efficiency (DE) and average degrees of freedom (DOF) for lightning occurring in each cell. If the estimated detection efficiency or average degrees of freedom drops below threshold, the cell will be flagged (filled with a color) indicating that it had low DE or low DOF.

Cells that are flagged should be regarded as being less reliable at detecting lightning events. This does not mean that the network is failing to detect lightning events in the region, just that it is more likely that events will be missed.

  1. To view Network Health on the map, select it on the weather product pane.
  2. Hover your cursor over a cell to see a short description of its status.
  3. Use the Opacity field to adjust the opacity of the colored cells.

    The opacity can be set in the range of 0 percent (completely transparent) to 100 percent (completely opaque).

You can not adjust the colors or thresholds associated with Network Health. These values are determined and set by the system administrator in the vsoweb-override.ini file based on the number and spacing of lightning sensors in the network. If Network Health is always showing down, ask your system administrator to review the threshold settings.
