00:00:01,900 --> 00:00:04,133

What you’re seeing here is a model,

3

00:00:04,366 --> 00:00:07,933

specifically of carbon dioxide moving through the atmosphere,

4

00:00:08,333 --> 00:00:11,333

driven by wind patterns and circulation.

5

00:00:12,833 --> 00:00:15,666

To create this model, billions of data points,

6

00:00:15,666 --> 00:00:19,466

informed by data collected from satellite and

ground-based measurements,

7

00:00:19,733 --> 00:00:22,900

Were run through powerful supercomputers to scale

8

00:00:22,900 --> 00:00:25,900

observed behavior to a global stage.

9

00:00:26,333 --> 00:00:30,933

What makes this model stand out is that it's super high resolution,

10

00:00:31,333 --> 00:00:34,700

128 times higher than a typical weather model

11

00:00:34,766 --> 00:00:39,066

and 500 times higher resolution than a typical climate model.

12

00:00:39,666 --> 00:00:44,500

This means we could focus on individual points

like power plants and forest fires,

13

00:00:44,733 --> 00:00:49,766

and see, in extreme detail, how these plumes move and get mixed in the atmosphere.

14

00:00:50,866 --> 00:00:53,333

Now, why is this important?

15

00:00:53,333 --> 00:00:56,433

Because by creating these high resolution models,

16

00:00:56,466 --> 00:01:01,833

NASA scientists are able to better understand

the behavior of Earth's interconnected systems,

17

00:01:02,033 --> 00:01:05,900

like how plumes of CO2 interact

and spread with weather systems.

18

00:01:07,066 --> 00:01:09,766

For instance, you can clearly see the impact

19

00:01:09,766 --> 00:01:12,766

the day-night cycles have on CO2 emissions.

20

00:01:12,933 --> 00:01:16,366

This is due to daily fluctuations in human activities,

21

00:01:16,466 --> 00:01:21,000

cycles of photosynthesis, and fires flaring up and dying down.

22

00:01:23,033 --> 00:01:25,700

Our ability to run such a simulation

23

00:01:25,700 --> 00:01:30,000

allows us to see how individual data points influence the larger picture,

24

00:01:30,466 --> 00:01:33,966

uncovering previously unknown atmospheric relationships,

25

00:01:34,566 --> 00:01:37,933

and help us better understand the complexities of our atmosphere.
