#2Am I missing something?
I can’t find a way to the current maps of lightning strikes.

There are hourly and daily maps [0]. But there is an alternative live map at https://map.blitzortung.org/
Re: World Wide Lightning Location Network
#4What is the diameter of each point? Aka how localised can they determine where the lightning is? Are we to assume the centre is where the lightning is? As I can't seem to find this information which I feel would be quite useful.

> When the time of group arrival is measured with 100 ns absolute accuracy by several widely spaced receivers, it is possible to locate lightning to within https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020GL09...

#6There's also Blitzortung.org which is a very interesting project.
They are receiving Sferics on the lower HF frequencies and tag them with GPS timestamps (with the PPS signal they are in the Nanoseconds precision range). A central server will then do the triangulation.
All with off-the-shelf hardware (STM32, etc.).
Their service is stable for many many years now.
(Offtopic: The STM32H7 ADC is great for many many things)

#7See also the excellent https://www.lightningmaps.org, an additional service of the excellent Blitzortung.or crowdsource project

Whenever it thundered I used to love to take out my shortwave radio, tune into some empty frequency and be able to hear each individual lightning strike in realtime (even more realtime than the speed of sound would allow!)
Re: World Wide Lightning Location Network
#9Nice! Need to implement realtime lightning data in a project soon, WIS2 is great for overall weather details but doesn't have a good temporal lightning resolution. Has anyone reached out to both and done that recently with WWLLN and/or Blitzortung?
The former seems to have better coverage especially across the southern hemisphere.
Re: World Wide Lightning Location Network
#10It seems like these kind of maps suffers enormously from the Mercator projection. Something better should really become the default for such usecases.
