LightningMaps.org is a map that shows lightning strokes around the globe in real time. The site gathers data from radio frequency signals that collect information on where lightning strokes occur. This is a community driven website so the information is crowdsourced and does not come from one specific governmental agency. Operators at radio frequency stations submit their information and the website then creates digital markers at the locations where lightning is being recorded. Due to a large network of operators sending information, the accuracy of the strokes is about one mile. This system covers specific areas in Europe, America, and Oceania. The website also stores strokes for up to 24 hours.
This website is especially interesting because amateur weather scientists can get involved recording lightning and adding to a global database. Also, this website acts as a good supplement to people who are looking to follow storms in real time. The website is easy to use with just a few buttons and four different overlays.
