  1. MétéorageLightning data for flood monitoring Marc Bonnet V.P. International October, 2011

  2. Agenda • Company overview • Lightning data • Lightning phenomenon and detection principles • Lightning data in Poland • Applications for flood management • Tools • Examples of use in Civil Security applications

  3. Based in Pau - France • A private French Company created in 1987 • A subsidiary of Météo France (since 2001) • Our Know-how • Operation of the French Lightning Detection Network, • Development of lightning operating systems (CATS) and application software (Observation), • Production and marketing of lightning services for end-users in Europe (France, Switzerland, Belgium, Luxembourg, U.K.) • Engineering for Lightning Detection Network • Météorage is granted with the ISO 9001:2008 Quality Standard.

  4. What is lightning ? From Cloud … • A transient electrical discharge • Typically occurs in thunderstorms, but occasionally in snowstorms, sandstorms, and volcanoes • Types of Lightning • Cloud-to-ground • Intra-Cloud • 70% of lightning remains in cloud • A complete lightning discharge is known as a flash • A flash is composed of multiple strokes, each one being producing a charge transfer to ground … to Electricity

  5. Benefits of ground based lightning detection networks • National coverage : the full information is available anywhere within the territory • Data Quality: an homogeneous level of quality • Reliability : the network is supervised and maintained 24h/24 and 7d/7 • Network effect when extending the coverage • Lightning information : • Impact information (date, position, intensity, polarity, accuracy) • Statistics from a National Data Base • Centrally operated and nationally available end-user products: • Real time information • Archived data • No investment, no maintenance • Provide a different measure • A complement to radar, satellite or rain gauges Optic Acoustic Electro- magnetic Electro- static

  6. Lightning in Poland Key points of lightning detection in Poland PERUN system (9 sensors) works operationally from 2002 Data is archived continuously Data is used by synoptic, aviation, power lines 2010 upgrade of visualization software 2011 network and system upgrade preparations System is owned by IMGW IMGW has its own service crew maintaining and administrating the system Lightning data characteristics PERUN system detects cloud-to-ground and intra-cloud data Information about polarity (positive, negative) and about current intensity in discharge channel is available 6

  7. Lightning in Poland Lightning density map in Poland, for 2010 7

  8. IMGW’s projects for lightning data • Institute of Meteorology and Water Management National Research Institute is the largest provider of hydro - meteorological data, products and services on the Polish market • IMGW has been developing its data and products for remote sensing of lightning using PERUN system for 10 years • Using many years of experience and vast knowledge on meteorology, IMGW is looking for possibilities of wider use of lightning data in other sectors of the economy than currently exploited • The IMGW's current goals are: • public awareness of the significance of information on lightning data and possible consequences of lightnings • development of an early warning system of impending lightning hazard • improvement of distribution system of lightning data and warnings • reach the largest possible number of users • Currently IMGW plans to cooperate in the development of appropriate tool to achieve those goals

  9. Real time applications Observation Jobs: An end user software designed to display, process and analyze lightning events in real time or from recorded data. Lightning Alarm: A service designed to warn the end user when a storm approaches his region and help him apply ad hoc procedures Area undersurveillance Display Message

  10. Civil Security applications • Flood crisis management: • Lightning is an early indicator for heavy rains • Lightning provides a first level of alarm • Good correlation with other type of data (radar,…) Lightning-rain correlation Document by Prédict Montpellier • Forest fire monitoring: • Lightning information allows to prevent • fire extension • Planning for crew management • Site survey planification Lightning layer on customer GIS
