00:00:02,302 --> 00:00:08,775
In early May 2023, fires ignited across 
western Canada due to unusually hot and dry weather.

2
00:00:08,775 --> 00:00:14,114
NOAA satellites watched as the fires raged,
burning about 1 million acres.

3
00:00:14,114 --> 00:00:18,885
Alberta and British Columbia issued 
evacuation orders for areas affected.

4
00:00:18,885 --> 00:00:21,855
As of May 8, many of the orders were downgraded

5
00:00:21,855 --> 00:00:25,025
as cooler weather arrived.

6
00:00:25,125 --> 00:00:28,561
GOES-18 watched the fires spread

7
00:00:28,561 --> 00:00:32,198
and produce smoke across the region.

8
00:00:33,867 --> 00:00:39,639
The ABI instrument on GOES-18 observed the formation of

9
00:00:39,639 --> 00:00:45,145
pyrocumulonimbus clouds from intense fires in Alberta.

10
00:00:48,448 --> 00:00:54,521
The widespread movement of smoke was also monitored by

11
00:00:54,521 --> 00:01:00,493
GOES-18 and GOES-16 in near real-time.

12
00:01:01,561 --> 00:01:07,033
JPSS satellites NOAA-20 and Suomi NPP 
measured the optical depth of the smoke.

13
00:01:07,033 --> 00:01:12,138
Data collected helps forecasters predict where the smoke will move.

14
00:01:17,310 --> 00:01:26,219
VIIRS imagery from the satellites also helps identify hotspots.

15
00:01:28,054 --> 00:01:40,200
Nighttime imagery also reveals the spread of the fires.

16
00:01:42,202 --> 00:01:46,873
The data collected by NOAA satellites help responders determine what

17
00:01:46,873 --> 00:01:51,377
areas will be impacted and manage the wildfires.

18
00:01:51,377 --> 00:01:58,351
As the Northern Hemisphere heats up, 
NOAA satellites will keep watch for wildfires.
