You dr googled 'lightning data colorado' and came up with the usual?
ie Colorado Lightning Resource Page
so obviously none of those were appropriate, was there nothing there that was useable?
Yes, I am aware of that and that is the only one that I know of. No dataset but there must be one somewhere and it would BE nice to have one to do some analysis ....
I think there are some companies that sell it out there but I do not want to pay for it.
