Lightning Detection Software, Version 1.0
To fully understand the implementation of this feature it is recommended that you experiment with it by
enabling and disabling linking while changing the values. After you are done experimenting you can reset the
kernel to reset all ranging correction values to zero.
Ranging kernel sectors are automatically de-rotated which means that you do not have to account for any
antenna alignment you have made while calibrating ranging. This means that you should modify ranging
kernel sectors where storms are actually being shown on the map, without having to account for any antenna
alignment that was made previously.
Calibration values
One unit of correction is equivalent to approximately one kilometer for the raw component of the strike signal.
However, because TRAC modifies the location of each strike before it is plotted, the unit-to-distance
relationship will always be altered to some degree, either upwards or downwards.
Negative values (blue color) will bring strikes closer towards center, positive values (red color) will push
strikes out towards edge of the map.
Enabling 2x effect boost will double the power of each unit of measurement. The actual ranging kernel value
will not change, only its power.
How to calibrate
The recommended procedure when calibrating ranging is to first adjust the General ranging correction so that
NexStorm ranges strikes as accurately as possible; then use the Segmented ranging for additional
corrections required for the ranging to become optimal. Remember to have a great deal of patience when
calibrating, this is not something you can expect to complete in a couple of days. It is of little use to calibrate
on single, sporadic strikes or very weak storms. NexStorm accuracy normally increases with increased
lightning activity so your best bet is to calibrate on storms that individually have strike rates of 5 strikes per
minute or above.
To verify the new calibration settings you must allow the program to process several strikes before any
changes will become evident. Calibrating ranging on real-time storms can therefore be time-consuming so the
preferred way of doing this is by using the Replay feature.
