Vaisala Thunderstorm CG Enhanced Lightning Sensor LS7001

Cloud-to-ground lightning detection accuracy

The LS7001 is a compact, lightweight sensor with optional indoor mounting capability that detects low frequency (LF ) signals using magnetic direction nding combined with time- of-arrival technology to deliver higher detection efciency, location accuracy and redundancy than any other method for detecting cloud-toground lightning strokes.

The LS7001 is a cost-effective solution for customers demanding high reliability, ease of installation and ease of maintenance.

CG Enhanced Lightning Sensor specializes in cloud-to-ground lightning sensing with lightning efficiency and excellent accuracy in location and lightning parameters using combined LF magnetic direction finding and time-of-arrival lightning sensing technology. LS7001 also detects survey-level (10-30%) cloud lightning and cloud-toground lightning at long ranges (>1500 kilometers).

Application focus on lightning tracking

The CG Enhanced Lightning Sensor LS7001 provides real-time data that is recommended for operations focused on tracking cloud-to-ground lightning threats to ground-based assets at risk:

• Aviation

• Defense

• Forestry

• Meteorology/Climatology

• Power Utilities

• Telecommunications
