Vaisala Enhances Accuracy and Performance of Its Global GLD360 Lightning Data
(Thomson Reuters ONE) -
Vaisala owns and operates the leading global lightning detection network, the
Global Lightning Dataset GLD360, which now offers lightning data with greater
location accuracy, improved polarity classification and peak current estimates.
These enhancements in data quality will help customers make more informed
decisions, increase operational safety and efficiency, and deliver better
services.
Vaisala has implemented a new processing algorithm that allows the global
network to identify the location of a cloud-to-ground lightning stroke within a
range of 2-5 kilometers. Polarity classification accuracy now stands at better
than 90 percent, while peak current estimates have been improved to be accurate
within 25 percent of the peak current value. The GLD360 is the only global
lightning dataset that provides polarity and peak current estimates for
lightning events.
"For the first time, quality lightning warnings are now possible on a global-
scale," says Nick Demetriades, Offering Portfolio Manager for Vaisala's Airports
business.
"The significant improvement in the GLD360 data quality due to the vastly
improved location accuracy of the global network, combined with its ability to
detect approximately 70 percent of all cloud-to-ground lightning flashes, will
improve the safety and efficiency of airport operations across the world."
As Vaisala's global lightning detection network provides uniform coverage with
high detection efficiency over the entire world, the GLD360 has more lightning
information than any other comparable dataset in the world with daily counts
routinely exceeding 1.5 million events.
Vaisala's GLD360 is now able to locate and characterize lightning in areas of
the world where meteorological observations may be partially lacking or absent.
Data from the network can be easily assimilated into weather models to improve
short-to-medium term weather forecasts. In addition, it can be used as a proxy
for weather radar information in areas with limited or non-existent radar
coverage.
Since Vaisala owns and operates the global network and delivers lightning data
as a service, customers can access the information available in the GLD360
without having to make substantial hardware investments.
