![]() ![]() Right now I use the above web sites for map viewing, and use the app on my tablet as a lightning alarm that will even wake me up if storms are firing in my area. The apps are still a little buggy, and the map views don't work well. Android and iOS apps: Blitzortung has free apps available that are quite useful, in that they have alarms that can be configured to go off if lightning happens within a set range of your GPS location.This map is more resource-intensive, and has a tendency to crash now and then in some browsers. The audio 'ticks' will only sound for strikes that happen in the visible map area, useful if you want to keep a browser window open and be alerted of storms that are producing lightning within a specific area. Zoomable Web Map: This map is good if you want to zoom into a specific area.While it can't be zoomed, it is the most 'lightweight' of the sources in terms of browser resources. ![]() Full USA Web Map: This is a non-zoomable map of lightning strike data in the USA.Here are the ways to view Blitzortung data: More volunteers building sensors will help the network's accuracy improve, however - I plan to do it at some point. You really don't need a sensor right now if you live in the USA and most of Europe, as there are plenty of them operating now to provide good data. I use this source daily! The plans for making the devices are free, but to get a sensor, currently you must build it yourself from sratch. It now has lightning data for the US, and the data is accurate and up-to-date. It's the lightning equivalent of amateur weather stations providing data to sites like Weather Underground. Blitzortung: This is an open-source network consisting of home-built sensors that originally started overseas.Ground strike points on the maps are marked with dots, plus signs (for positive-flash strikes), or minus signs (for negative-flash strikes).Īlthough comprehensive access to lightning data is generally fee-based, there are many free lightning data sources on the internet, many of them real-time (or slightly delayed). This data is used to create detailed maps of lightning strikes on a real-time basis. The data collected by multiple sensors allows the location of strikes to be calculated via triangulation. These radio waves are used to calculate how far away a strike is in relation to the sensor. Today, private companies and open-source groups operate networks of special sensors that can detect radio waves produced by lightning. Lightning strike maps are images that display the locations where cloud-to-ground lightning strikes have occured. ![]()
