Time of Difference of Arrival Advanced Display

The TOdA (Time Of difference of Arrival) system is a network based lightning triangulation method employing multiple volunteer detection sites across Europe and soon to include North America. It provides high accuracy detection which augments the participating stations existing lightning detection systems.Worthing Weather is part of this project and supplies data to the TOdA network.

The technology utilises the highly stable and immensly accurate GPS timestamp to tag each potential lightning strike which is then mathematically analysed and passed along to a central server where it is subject to further analysis and matching with other detection signatures from alternate stations. When 4 or more stations confirm the same strike it is recorded along with its type (+/- CG or IC) and made available for display, in the above case on a composite vector map with frequent updates.

Theoretical accuracy is dependant on the number of stations detecting the strike and the geometry of those stations in relation to the strike itself, however in theory this is between a few Kilometres down to just a few hundred metres which is quite impressive. Our display software is in beta with frequent updates.

If you have any pictures of weather related events then please send them to us.

They will then be displayed here for others to see. To see the pictures, click on Pictures in the menu on the left.

We have had some interesting events this year including wind speeds of over 100 miles per hour in Worthing which led to a tornado developing in Farnborough. Pictures of such events, lightning storms, interesting cloud formations or other severe weather events would make interesting viewing.
