One place to start is an option in the s.menu
command that converts a site file into a raster
file that represents the number of sites within
a raster cell, which you would set according to your
needs beforehand with g.region. This would produce
a raster map showing the number of lightning strikes
per square _______. I suppose that you could then
use r.mapcalc to divide that raster map by the total
number of lightning strikes * 100. This would give the
percentage of strikes per square _______.

I think this option exists (number 7), on the sites menu.
