Page 4 / July 2009 / Nikki Hembury / ©Vaisala Vaisala Technology Combines Best Techniques for Total Lightning Detection  Vaisala Thunderstorm Lightning Sensor TLS200  Use VHF interferometry techniques for the finest cloud lightning detection – greater than 90% detection – plus mapping of the full cloud channel in 2D – Similar to LMA cloud and LDAR II cloud mapping  Use proven LF combined Magnetic Direction Finding (MDF) plus Time of Arrival (TOA) techniques for accurate and finest Cloud to Ground locations.

Page 5 / July 2009 / Nikki Hembury / ©Vaisala VHF total lightning mapping versus VLF/LF cloud lightning detection networks Flash-scale Blue – VHF cloud lightning mapping Red – VLF/LF cloud lightning detection  Detect a fraction of all cloud flashes (typically 5-50%)  Only maps areas around the initiation points of cloud flashes

Page 7 / July 2009 / Nikki Hembury / ©Vaisala TLS200 Sensor Total Lightning Detection (>90% CG+IC with mapping)  Technology:  VHF Interferometry combined with LF Time of Arrival (TOA) and Magnetic Direction Finding (MDF)  VHF for 2D cloud lightning aerial mapping  LF for accurate CG detection (as used in NLDN®)  Benefits:  Sigmet® digital signal processing for improved signal to noise ratio (10dB improvement)  Longer baseline network, fewer sensors to cover same area as compared to VHF-TOA (LDAR II) and VHF-ITF (LS8000)  Accurate LF CG data, improvements to 150 meter Location Accuracy  Lower overall cost of ownership for a network  VHF only option to further reduce costs to owners  Easy to install, service and maintain

Page 10 / July 2009 / Nikki Hembury / ©Vaisala VHF performance results / field results  Data shows that the digital interferometry (TLS200) implementation is capable of delivering >90% DE at a range of almost 200km.  This is almost 2-fold improvement for detection in VHF as previous products.

Page 11 / July 2009 / Nikki Hembury / ©Vaisala Vaisala TLS200, IC mapping  One example:  Extension NS = 30km  Extension EW = 10km  Duration ~100ms  621 VHF sources

Page 12 / July 2009 / Nikki Hembury / ©Vaisala NLDN® Total Lightning expansion  NLDN® expansion to TLS200 product  The best detection capability  Properly grouping cloud pulses without exaggerating DE claims  Validation through third party studies and ground truth/high speed video campaigns
