This is the Schumann strike count viewer.  It's job is to show real time strike activity and archive the days results at the end of the day.  As shown below it also contains an internet browser that has the ability to see real time world weather maps.  The real time varies from 20 minutes to several hours depending on the type map.  The calendar is for retrieving past archived plots.

The graph itself is saved every ten minutes for FTP  to a real time site page.  The days archived plot can be reconstructed and saved for printing.


This example points out a few things that might not be obvious.  Browser buttons "Toggle" to go into and out of "Browser" mode for instance.  The mode window showing

"Real Time On" toggles between that and the "Archive" mode.  The graph is collected from the latest collector product file every 10 minutes and displayed.  This is not critical time wise

as the Viewer is simply displaying the stored collector array and running independently of the collector.  There is a file activity sync going on between programs.  You cant update the

viewer for instance if the file is being used by the collector at the time you press the update button.  At zero (0) /10 update time it will block file use.  Retry in a few seconds if that happens.


This example gives an idea what your looking at on the chart.  The red trace is the averaged amount of strikes out of the 7.8Hz Schumann cavity.  You can see the browser map

showing activity world wide when this chart was made.  Heavy actiity in Africa and previous heavy activity in Asia.  Asia is now in the dark and dieing down count wise.

The individual counts can be seen by the total group if pressing the "View Array" button as shown on the left.  Under the grap is an array view bar that can look at each

each indexed value of the day.  There are 144 ten minute collection counts each day.  The lightning radar strike collector has to be set to 10 minute collections also.  More graph

controls are shown below when the browser is toggled off the screen.


This example shows the buttons and settings below the graph.  These control the graph trace which as you can imagine is quite wild in its raw form.  We are detecting noise

with in noise of the Schumann Cavity.  Not an easy task with thousands of lightning strikes going at the same time world wide into the cavity.  So these have to be tamed to make

any sense out of it.  To understand what were doing you need to see this simple graphic of the signals as the viewer sees them arrive.  The manual threshold keeps the signal from being

acted upon by the gain control.  We are only interested in the above threshold level to be able to count the variance between background and peak value strikes. The manual threshold

control should always be set above the low value of the variance as shown.  Later this adjustment may become automatic but for now set it 2 values above the low reading on the viewer.

The background setting works in conjunction with the reference setting to move the trace in the vertical.  There is no hoz. adjustment as this is based on time.

The gain background and reference settings allow you to find the correct settings to fit the red trace to the background standard curves.  This is a relative thing except

you can view the actual count of strikes by looking into the array.  The viewing bar below the graph gives the index number and count value anywhere along the trace.

The first data and last data is simply that inside the array.  If say starting the trace in the middle of the day some where, you can find that point.  The AVG selectors

are controls on how much averaging is applied to the trace.  You can change these and  press the update graph button to see the effect it has. 0 is of course n o averaging.

Notes typed into the collector note window will be appended to the end of the array and be archived along with the data for the day.  This can be viewed out of the archive

 file by looking at the array file with the view button.
