Europe imposes restrictions on the commercial use of lightning data and recovers its cost through end-user charges. Though SFLOC data is publically available, you must contact the data supplier to inquire about your status if you are using the information on a commercial basis. The responsibility rests with the user to ensure that they are not violating any rules or national regulations. The SFUK bulletin's point of contact is the British Met Office ( / tel. +44 (0)1392 885680).Europe's primary lightning network consists of five stations in the UK, one in Cyprus, and one in Gibraltar. The stations listen for static and use triangulation of the time delay to pinpoint the location. This is encoded to the nearest half-degree, yielding a resolution of about 40 km. The commonly-available British bulletin (SFUK) has a domain of 40W to 40E and 30N to 70N. The time period for each bulletin is 30 minutes, and a new bulletin is generated every 30 minutes. The SFUK is based on the WMO FM 32-I SFLOC code form but is adapted under a national variation. The British Met Office does have a new system online that can pinpoint lightning within 100 meters, however this data is not publically distributed. Contact the Met Office if you need access to this data.

Using this information, Digital Atmosphere will plot lightning strikes to the nearest half-degree (about 40 km resolution).
