00:00:01.167 --> 00:00:03.269
Planning to watch the eclipse?

2
00:00:03.269 --> 00:00:06.840
With just your smartphone
and a thermometer, you can help contribute

3
00:00:06.840 --> 00:00:10.944
to our understanding
of how the eclipse affects our atmosphere.

4
00:00:11.011 --> 00:00:15.015
Even if you will only experience
a partial eclipse from your location,

5
00:00:15.115 --> 00:00:18.284
your observations are still valuable.

6
00:00:18.385 --> 00:00:21.254
Start
by downloading the GLOBE Observer app.

7
00:00:21.254 --> 00:00:24.591
You will need a connection to the internet
and access to email

8
00:00:24.591 --> 00:00:26.659
in order to set up an account.

9
00:00:26.659 --> 00:00:30.864
So you should plan to do this step
before the day of the eclipse.

10
00:00:30.930 --> 00:00:35.502
Complete the brief in-app tutorials
for Land Cover and Clouds.

11
00:00:35.568 --> 00:00:39.139
Don't worry if the Eclipse tool
isn't visible in the app yet,

12
00:00:39.239 --> 00:00:42.575
it will appear closer to the eclipse.

13
00:00:42.642 --> 00:00:45.311
Next, find a thermometer that you can use

14
00:00:45.311 --> 00:00:48.848
to measure air temperature
at your precise location.

15
00:00:48.915 --> 00:00:52.118
Remember, the temperature in your weather
app is from a weather

16
00:00:52.118 --> 00:00:54.888
station that may be far away.

17
00:00:54.988 --> 00:00:57.390
You can
check the accuracy of your thermometer

18
00:00:57.390 --> 00:01:00.360
by putting the probe in an ice bath.

19
00:01:00.393 --> 00:01:02.762
After 10 minutes,
the thermometer should read

20
00:01:02.762 --> 00:01:06.666
between plus or minus 0.5 degrees Celsius.

21
00:01:06.666 --> 00:01:10.203
On the day of the eclipse, plan
to take observations

22
00:01:10.203 --> 00:01:14.374
for an hour or two before
and after the eclipse.

23
00:01:14.441 --> 00:01:17.077
The longer that you take
measurements, the easier

24
00:01:17.077 --> 00:01:20.447
it will be to see changes in the air
temperature.

25
00:01:20.547 --> 00:01:23.149
Be sure to pack everything
you need to be safe

26
00:01:23.149 --> 00:01:27.020
and comfortable during the eclipse.

27
00:01:27.120 --> 00:01:29.956
Look for an area
with a clear view of the sky

28
00:01:29.956 --> 00:01:32.792
while being cautious of uneven ground,
moving

29
00:01:32.792 --> 00:01:35.795
vehicles, and other hazards.

30
00:01:35.962 --> 00:01:40.567
Once you're set up, launch the GLOBE
Observer app and open the Eclipse tool.

31
00:01:40.633 --> 00:01:44.003
You'll start by choosing
between Celsius and Fahrenheit

32
00:01:44.070 --> 00:01:47.073
and selecting the type of thermometer
that you will be using.

33
00:01:47.173 --> 00:01:51.478
Next, use the Land Cover tool
to document your observation site.

34
00:01:51.578 --> 00:01:56.149
You will take photos in each direction,
as well as, up and down.

35
00:01:56.216 --> 00:01:59.619
Include your thermometer
in one of your photos.

36
00:01:59.686 --> 00:02:00.186
Enter your

37
00:02:00.186 --> 00:02:04.290
first temperature measurement
and observe the sky using the clouds tool.

38
00:02:04.390 --> 00:02:06.926
The app will prompt you
to take temperature measurements

39
00:02:06.926 --> 00:02:12.365
every 5 to 10 minutes leading up to
and after the eclipse.

40
00:02:12.432 --> 00:02:14.734
If you notice any changes in the clouds,

41
00:02:14.734 --> 00:02:18.338
use the Clouds tool
to document these changes.

42
00:02:18.404 --> 00:02:22.609
Feel free to add captions to your photos
with observations of the wind,

43
00:02:22.709 --> 00:02:27.347
animal behavior,
and any other changes that you experience.

44
00:02:27.413 --> 00:02:30.350
Now you're all set to observe the eclipse.

45
00:02:30.350 --> 00:02:33.686
Remember to take a break
during maximum eclipse to enjoy this

46
00:02:33.686 --> 00:02:38.458
incredible experience.
