#GLD360
This means this is the first documentation of volcanic lightning with Hayli Gubbi #volcano.

185 volcanic lightning events detected by Vaisala’s Global Lightning Dataset GLD360.

A Christmas present for you soccer fans.

At the @ametsoc.org Annual Meeting next month, I'll be presenting a FIFA World Cup lightning risk assessment.

To do this, I've taken NLDN/GLD360 lightning data during the World Cup period 2016-2025. Here are the pretty maps.

I've got 47,085 CGs over Alaska between 7 am 6/16 and 7 am this morning from GLD360. 😳

And it has a significant outbreak of globally detectable lightning around the center of circulation, like Milton.

Lightning data via Vaisala GLD360.

Lightning data from Vaisala's Global Lightning Dataset GLD360.

Red icons are cloud-to-ocean events, black icons are in-cloud events.

Shortly before 1 pm on September 18 in Westland, New Zealand, a thunderstorm produced a massive 176.5 kA positive CG stroke that caused significant damage to the radome and probably damaging the electronics as well.

Standing high above the ground, radars are often hit by lightning.

That is not an ideal map to use for this case, because it only shows 6 months of data from 2010 when the GLD360 network was brand new.

Here are 10-year maps showing lightning density surrounding the World Cup stadiums during the tournament period:

I stole this from the Worldcup subreddit because it makes a very good point.

The Vaisala Xweather Annual Lightning Report came out today. They count the number of #lightning events detected by the National Lightning Detection Network and Global Lightning Dataset GLD360 that occurs each year.

Wisconsin saw 2,136,300 total lightning events in 2025, 26th most in the U.S.

That’s a misleading chart drawn from a too-limited time period that excludes the seasons where other regions see their worst storms.

A multi-year average from the same source & a density map look very different. The DRC has a significantly higher density of lightning strikes than any other country.

It's Vaisala Xweather Annual Lightning Report Day!

I used to lead development of this report before I came to Wisconet (the last one I lead won a Finnish Comms Award); glad to see a lot of things we did have continued 2 years later.

2.2 billion events detected globally
209 million in the U.S.

Vaisala owns and operates 2 networks - NLDN and GLD360. The two networks can be complementary, especially as you get further from CONUS.

Vaisala has also sold/installed >100 networks for customers globally.

Earth Networks, Nowcast, TOA, and others install their own networks.

It's backwards!

No matter where lightning is taking place, even in a tropical cyclone off the coast of Madagascar, GLD360 can give you the latest data, and Thunderstorm Manager can give you satellite and radar information.

I'm not sure how high the flash rates from GLM got in some of the other significant storms lately (like Ian or Milton), but while Melissa had a lot of eyewall lightning detected by GLD360, it certainly didn't compare to Milton last year.

bsky.app/profile/cowe...
36 hours of (mostly) eyewall lightning from Milton.

Red diamonds are CG, black circles are IC.

Milton's done something I've never seen before - regenerate an Enveloped Eyewall Lightning Signature after going through an Eyewall Replacement Cycle 😳

Over 100k events in eyewall!

GLM does a good job of detecting the expanse of lightning flashes and the optical energy produced by them. NLDN/GLD360 detect the point locations of lightning strokes, their peak currents, and whether they are in-cloud or cloud-to-ground.
January 18, 2025 at 4:04 AM
GLM detects about 70-80% of what NLDN sees over the eastern 1/3 of the U.S. (agupubs.onlinelibrary.wiley.com/doi/full/10....)

The Global Lightning Dataset sees globally, beyond GLM and NLDN and has high performance (also seen in the article).

Loop of #lightning data from #Ulawun #volcano in 10 minute intervals from 0120-0130 UTC through 0800-0810 UTC. Red dots are Cloud-to-Ground lightning, black dots are In-Cloud lightning from @VaisalaGroup GLD360.

The last 24 hours of #lightning in extremely powerful Typhoon #Hagibis. The Enveloped Eyewall Lightning (EEL) Signature is readily apparent. Data from @VaisalaGroup #GLD360.

Volcanic eruption at #TaalVolcano with AMAZING #volcano #lightning display. Remind me later to get counts. Data from @VaisalaGroup #GLD360. #VaisalaDigital #AMS2020 @janinekrippner @C_MarieSmith @volcaniclastic @simoncarn @CorCima

24 hours of #lightning in Cyclone Harold from @VaisalaGroup GLD360
December 8, 2024 at 6:15 PM
Big circulation of #AmphanCyclone in the Bay of Bengal visible in watching the loop of #VaisalaDigital GLD360. An increase in eyewall region #lightning also evident in the most recent frames.

#Andreas has formed in the Eastern Pacific: http://www.nhc.noaa.gov/#ANDRES #GLD360 data shows #lightning associated with him

. @COweatherman zoomed in view on the cluster in the eyewall of #Patricia. Lots of positive #lightning from #GLD360
December 8, 2024 at 8:55 AM
Absurd amounts of #lightning detected by #GLD360 in eyewall of #Patricia in the past 25 minutes.
