00:00:03,970 --> 00:00:10,410
On July 18, 2023, NOAA satellites watched the 
Midwest and eastern U.S. wake up to more smoke-filled skies.

2
00:00:11,277 --> 00:00:15,215
This comes after intense rain caused major flooding in two

3
00:00:15,215 --> 00:00:19,019
separate events over the past two weeks in the Northeast.

4
00:00:19,652 --> 00:00:24,224
A plume of moisture from the Atlantic Ocean led to heavy rainfall,

5
00:00:24,224 --> 00:00:29,596
resulting in flooding on already heavily saturated ground.

6
00:00:29,596 --> 00:00:37,337
Meanwhile, wildfires continue to burn across regions in Canada.

7
00:00:37,937 --> 00:00:44,077
Smoke from the fires has continued
 to move southward into the lower 48 states.

8
00:00:44,277 --> 00:00:46,913
The smoke traveled across the Midwest and as far south as Florida.

9
00:00:46,913 --> 00:00:49,049
More smoke is expected in the near future.

10
00:00:49,049 --> 00:00:53,953
NOAA satellites monitored conditions as the events unfolded.

11
00:00:55,088 --> 00:00:58,892
GOES-16 measured water vapor that was transported in the atmosphere,

12
00:00:58,892 --> 00:01:02,062
and tracked the storms that drenched the Northeast in near real-time.

13
00:01:11,538 --> 00:01:14,374
Meanwhile, GOES-16 and 18 watched the wildfires in Canada produce

14
00:01:14,374 --> 00:01:16,676
intense smoke.

15
00:01:16,676 --> 00:01:19,579
The satellites tracked the smoke as it moved into the central and eastern

16
00:01:19,579 --> 00:01:22,048
U.S., triggering air quality alerts.

17
00:01:24,451 --> 00:01:27,854
The ATMS instrument on NOAA’s JPSS satellites measured the moisture

18
00:01:27,854 --> 00:01:30,824
in the air and total precipitable water.

19
00:01:30,824 --> 00:01:34,127
The measurements help forecast where heavy rainfall will occur.

20
00:01:35,995 --> 00:01:38,965
Data from the satellites is also used to produce flood maps that help 

21
00:01:38,965 --> 00:01:41,935
with emergency response.

22
00:01:42,135 --> 00:01:47,073
The VIIRS instrument onJPSS satellites also provided data

23
00:01:47,073 --> 00:01:51,678
to help forecast where the wildfire smoke will affect air quality.

24
00:01:53,379 --> 00:01:56,349
As multiple atmospheric events impact the U.S.,

25
00:01:56,349 --> 00:01:59,319
NOAA satellites will help warn us of approaching hazards.

26
00:01:59,319 --> 00:02:01,154
