SCALAR network

Network coverage:


1996 – Elektroinštitut Milan Vidmar (EIMV) and Elektro Slovenija (ELES) joined resources in establishing first lightning localization system in Slovenia. The system based on three magnetic direction finders LLP.

1997 – Only after one year, with a great help from Finnish Meteorological Institute who contributed position analyzer software, the LLS was operational. It was utilized in National Control Center (ELES). Although the LLS was fully operational through out the lightning season, it was judged that data with poor timestamps accuracy has only limited value. The decision was brought that GPS synchronized sensors must be implemented.

1998 – In the beginning of June 1998 two LPATS III sensors were put in operation. They were processed together with 8 IMPACT Austrian sensors by Austrian Lightning Detection and Information System (ALDIS). Raw data from sensors were transmitted to lightning location analyzer in Vienna over public Internet. The lightning location data i.e. solutions are then retransmitted back to our computer centre. EIMV developed lightning information dissemination system based on Linux OS and JAVA technology. The LLS was named SCALAR which is an acronym for Slovenski Center za Avtomatsko Lokalizacijo Atmosferskih Razelekrtitev (Slovenian Centre for Automatic Localization of Atmospheric dischaRges).

1999 – Lightning data from the new LLS immediately showed benefits as lightning events could be easily correlated with events in power transmission system. Mayor improvements in software were made and new services introduced. Cooperation with Global Atmosfpehircs Inc. was established in which EIMV ported existing client/server suite for GAI needs. EIMV was a co-founder of the EUCLID cooperation.

2000 – Substantial customer growth and development of CorrelatorServer for the transmission power utility ELES. The Correlator is a software tool that processes transmission faults caused by lightning with lightning data. The tool is primarily used in close support to the maintenance crews in the field trying to locate the fault.

2001 – Completing the correlator software and begging of development of a new HTTP light weight client FlashDisplay. This display software is JAVA applet and utilizes HTTP for near real-time presentation of lightning on the raster images.

2002 – Besides this a CompositeDisplay for displaying radar images overlapped with lightning information was introduced and immediately utilized by all Slovenian transmission and distribution utilities.

2003 – Introduction of a new version of a vector graphic client FlashClient with improved and faster GUI and high resolution flash density map (HRFD). HRFD maps are crucial in determining the lightning exposure of objects like transmission or distribution lines, telecommunication towers, etc. HRFD maps are calculated based on the error ellipse, which is part of the lightning location and are typically calculated with a resolution of 100 x 100 m.

2004 – New mile stone was reached with an unified CorrelatorServer which is able to correlate transmission and distribution lines faults in a full concurrent manner. Besides this a CompositeDisplay for displaying radar images overlayed with lightning information was introduced and immediately utilized by all Slovenian transmission and distribution utilities.

2005 - LS7000 sensor was put in operation at place Bate.
2008 - LS7001 sensor was put in operation in Jelše pri Krškem.
2009 - sensors were put in operation in Croatia at place Velika, Pula and Rogoznica.
2011 - sensor was put in operation in Serbia, town Niš.
2012 - two sensors were put in operation in Bosnia and Herzegovina, town Bigać and Rogatica.
2013 - sensor was put in operation in Montenegro, town Podgorica.

2013 - Introduction of a new version of a lightning mapping software ScalarFlashClient. A new modern user interface is based on JavaFX technologies. Software was evolved to overcome the time-consuming integration and to simplify the implementation of service variety. The ScalarFlashClient can' use services from several server domains where different Web Map Services can offer a different geographical information system to the end users. The lightning domain server platform also contains common services like the authentication and the authorization of the user. The user can now access the lightning data much easier and is able to perform data analysis and monitor weather data in real time. Custom GIS, alarming and correlation services can now be integrated in a whole new way.

2014 - sensor in Rogoznica was replaced with new sensor in Split.
