Good afternoon Ron & team,
Thanks for the effort in publishing this handy map.

I managed the South African LDN for 7 years and learned a lot during that time.
Using the GLD360 data in applications in the UAE now with Radar data ext.

The following are skewing the country results as its presented:
-The area of the country play a roll in the final per country result.
-The geographical diversity of the country also play a roll in where the most lightning occur.
For example: Alaska as part of the US has a high value and should be nearly the same as Canada.
In South Africa the North Eastern area have very high lightning density against the South Western areas. (Similarly, I expect over the USA)
Swaziland and Lesotho both much higher than SA.

Please consider a global lightning density with contours to show the peak areas.
The steps can be big not to clutter up the map.

Best regards
Karel
