00:00:02,635 --> 00:00:09,976
On June 2, 2022, NOAA shared striking first imagery
from the GOES-18 lightning mapper.

2
00:00:09,976 --> 00:00:17,017
Launched on March 1, GOES-18 is NOAA's 
newest geostationary satellite.

3
00:00:17,484 --> 00:00:24,457
Onboard GOES-18 is the Geostationary Lightning Mapper (GLM).

4
00:00:24,824 --> 00:00:29,763
GLM continuously detects and maps lightning activity

5
00:00:29,763 --> 00:00:33,833
over the Americas and adjacent ocean regions.

6
00:00:37,670 --> 00:00:43,276
Rapid increases in total lightning activity often precede
severe and tornadic thunderstorms.

7
00:00:43,276 --> 00:00:47,981
GLM helps forecasters identify intensifying storms.

8
00:00:49,449 --> 00:00:53,987
Recently, GLM monitored lightning activity within severe

9
00:00:53,987 --> 00:00:57,490
storms across the U.S.

10
00:00:59,659 --> 00:01:03,763
The instrument captured significant lightning activity in the

11
00:01:03,763 --> 00:01:08,101
derecho that moved across the Northern Plains on May 12-13.

12
00:01:09,102 --> 00:01:18,178
Scientists and forecasters can extract 3D information from GLM observations.

13
00:01:19,679 --> 00:01:23,616
This imagery reveals how GLM captures the evolution of individual

14
00:01:23,616 --> 00:01:27,787
storm cells that combine to form massive storm systems.

15
00:01:31,624 --> 00:01:39,466
Widespread weather events pose particular challenges 
for the aviation industry.

16
00:01:42,302 --> 00:01:47,307
GLM data helps pilots and air traffic controllers route flights

17
00:01:47,307 --> 00:01:52,145
to maximize safety and minimize economic impacts.

18
00:01:55,815 --> 00:02:01,721
GOES-18 is undergoing post-launch testing to prepare it for operations.

19
00:02:03,223 --> 00:02:10,096
NOAA plans for GOES-18 to begin operating as GOES West in early 2023.

 Geostationary Lightning Mapper

21
00:02:11,498 --> 00:02:12,932
Imagery from GOES-18 during the post-launch testing phase should be considered preliminary and non-operational
