First, a valid authentication message is sent to the connection. The Python socket library is used to establish a TCP socket connection to the ENLTN data feed. In this script, it is shown how to (i) connect to the ENTLN Data Feed using Python, (ii) parse out lightning data from the JSON payloads received from the TCP socket, and (iii) plot lightning strike locations on a map of the continental United States. Note that access to this datafeed is restricted to paying subscribers. I use it because it is satellite-based and therefore always works no matter where I am - I do not lose data if I don't have a cellular signal.This script maps real-time lightning strike locations in the continental United States using a TCP socket datafeed of lightning data from Earth Networks.Įarth Networks is a provider of global weather data and operates the Earth Networks Total Lightning Network (ENTLN), one of three lightning networks in the United States that provides real-time information about lightning strikes.Įarth Networks provides access to real-time lightning data from the ENTLN via a TCP socket connection, referred to as the ENTLN Data Feed. WxWorx is only an option for the most serious of storm photographers due to its cost. The median-level and top-level plans include realtime lightning data. Baron/XM WxWorx (Mobile Threat Net): I have been using the WxWorx system continuously since 2004.I have heard good reviews of this app, but have never used the lightning data option myself since I currently operate WxWorx. At last report, the app cost $9.95 to buy (one time charge), with the lightning data an additional $9.95 per year. Radarscope: Radarscope is a mobile app that has an option for lightning data to be added on.(The listing of these services are neither paid nor constitute an official endorsement) Now that Blitzortung is online in the US, I rarely use this link.įee-based services that include lightning data Their free map is delayed by at least 20 minutes, limiting its usefulness - but it is a good backup for monitoring lightning trends. Their data has generally been tailored for business and government clients, and their prices have been out of range for the average casual user. Vaisala: Vaisala is the owner of the original NLDN (National Lightning Detection Network).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.
