Vaisala Introduces a Unique Global Lightning Dataset

GENEVA - The dataset will provide lightning information throughout the globe to serve the world’s meteorological institutions and other weather-dependent users.

Consisting of lightning sensors distributed throughout the globe, the coverage and performance of Vaisala’s Global Lightning Dataset (GLD360) is unique, global, and real-time. GLD360 outperforms satellite lightning detection by enabling uniform global coverage and by providing the timeliest information on rapidly evolving severe weather situations. The network detects over two thirds of all lightning strikes coming to the surface of the earth and provides peak current information for cloud-to-ground lightning events. Additionally, the dataset provides information over oceanic regions where there is a shortage of real time weather observations.

“We have over 20 years of experience in thunderstorm systems in North America, and are now extremely pleased to launch a data solution that serves our customers on a global scale,” says Kjell Forsen, the President and CEO of Vaisala.

The potential application areas of Vaisala’s GLD360 data range from thunderstorm identification, hydrology and hurricane forecasting to improved high sea identification and climate change research. Additionally, aviation and marine routing will benefit from improved lightning data provision.

“Over the past five years, we have demonstrated that assimilating lightning data into mesoscale weather models can improve short-to-medium term forecasts. The superior coverage and performance of GLD360, particularly over data-sparse ocean regions, provides a unique opportunity to improve synoptic and mesoscale forecasts on a global scale,” says Dr. Steven Businger from the University of Hawaii.

The Global Lightning Dataset (GLD360) is the result of research collaboration with Stanford University. Vaisala’s leading expertise in environmental measurement combined with best possible technological knowhow has made this real-time, global network a reality.

“It is rewarding to see that this joint scientific and technological innovation will benefit a large number and variety of users in different parts of the world - not only the meteorological community but also climate change research,” stated Dr. Ryan Said from Stanford University.

Vaisala arranges a webcast press briefing about the GLD360 on Monday August 31 at 14:00 CET in connection with the World Climate Conference in Geneva, Switzerland. The webcast can be viewed at vaisala.magneetto.net
