Revolutionary Technology for Highly Accurate Lightning Detection -- Now Also Available on Linux®

TUCSON, AZ--(Marketwire - October 27, 2009) - The central processing software for Vaisala's lightning detection sensors is now available on a Linux® operating system. For the user, this means added flexibility, ease of use and lower ownership costs.

Vaisala Total Lightning Processor™ Series TLP100 and TLP200 central processing technology computes and displays information from the raw data provided by lightning detection sensors. It also monitors network performance continuously, allowing the user to validate that all sensors are operational and functioning to specification.

Both TLP™ series include Vaisala's patented location algorithm with propagation correction services, locating lightning activity with a precision range of 250 meters or less. The location accuracy has been scientifically validated in cooperation with third parties. Additionally, the TLP™ provides for a user-friendly web-based interface with performance tools, which can save up to 80% of the user's time in analyzing raw data and overall network performance, resulting in substantial returns on investment.

Vaisala's expertise in lightning data and information systems is based on extensive experience and investment in R&D. For the past 20 years, the company has owned and operated the National Lightning Detection Network (NLDN), a lightning detection network covering the United States. This year, Vaisala introduced a unique global lightning dataset, GLD360, with uniform coverage worldwide spanning oceanic regions where there has been a shortage of real-time weather observations.
