I understand that storing the binary image needs a vast space. However, I do not understand if there exist data records of individual lightning in JSON or another database. Or do you mean that historical data does not exist at all in any form?
Yes. Some such files exist. Some historic data was lost due to a server farm fire a couple of years ago. Excluding a few scientific research institutions, this data is ONLY available to registered station operators, with proper credentials and not available publicly. I'm not sure of the extent of storage since I rarely access it, but at one point it was limited to current as far back as perhaps one year.
