Tucson Airport Authority and Vaisala Partner to Improve Lightning Warnings for Airport Safety

Share Article

Vaisala's applications group and thunderstorm team have partnered with the Tucson Airport Authority (TAA) to study total lightning detection and warnings at Tucson International Airport (TIA). Vaisala has installed the most advanced lightning detection network, using the Vaisala Total Lightning Sensor LS8000, to track both cloud and cloud-to-ground (CG) lightning. The new total lightning mapping network installed in the greater Tucson area will now detect thunderstorms earlier and will provide the TAA operations team with critical decision making information in addition to data from Vaisala's National Lightning Detection Network (NLDN), which identifies approximately 95% of all CG lightning flashes.

Efficient lightning warning during thunderstorms is one of TAA's primary concerns. We welcome the opportunity to work with Vaisala as they complete testing on advanced lightning sensor technology. This partnership increases our safety promise to the airlines, the re-fuelers and others on the tarmac.

Daniel Morelos, TAA Director of Operations, stated, "Efficient lightning warning during thunderstorms is one of TAA's primary concerns.

This partnership increases our safety promise to the airlines, the re-fuelers and others on the tarmac."

Critical to the aviation industry, Vaisala LS8000 total lightning networks map over 90% of all cloud lightning flashes which typically precede CG lightning in approximately 70% of all thunderstorms in the contiguous U.S. For most thunderstorms, the area of cloud lightning activity is larger than the area of CG lightning activity. Several years of Vaisala lightning research has shown that regions where cloud lightning activity exists are at risk for CG lightning.

The results of this study are expected to include further improved operational efficiency, increased safety during fueling operations, including safety for tarmac and ground employees, and provide observable benefits in aircraft routing during take off and landing.
