This year, five new missions are taking off to investigate

2

00:00:05,000 --> 00:00:09,000

our home planet. From coast to coast, these missions will take a closer look at everything

3

00:00:09,000 --> 00:00:13,030

from sea level rise to snowstorms, all based right here in the United States.

4

00:00:13,030 --> 00:00:17,030

5

00:00:17,030 --> 00:00:21,000

6

00:00:21,000 --> 00:00:25,030

About 200 miles off the coast of San Francisco, the Submesoscale Ocean Dynamics Experiment, or S-MODE,

7

00:00:25,030 --> 00:00:29,030

will use measurements from a research vessel and three planes –

8

00:00:29,030 --> 00:00:33,000

a King Air, a Gulfstream and a Twin Otter, to look at how

9

00:00:33,000 --> 00:00:37,030

swirling ocean eddies affect the movement of heat between the ocean

10

00:00:37,030 --> 00:00:41,000

and the atmosphere. Autonomous wave gliders

11

00:00:41,000 --> 00:00:45,030

and ocean gliders will dive below the surface of the water, to get a full picture

12

00:00:45,030 --> 00:00:49,000

of the ocean and atmosphere.

13

00:00:49,000 --> 00:00:53,000

Together, the mission will collect data about temperature, salinity

14

00:00:53,000 --> 00:00:57,030

and ocean velocity to get a better understanding of how small eddies

15

00:00:57,030 --> 00:01:01,030

affect the upper ocean.

16

00:01:01,030 --> 00:01:05,030

17

00:01:05,030 --> 00:01:09,030

Traveling inland to the Midwest, the summer months can bring

18

00:01:09,030 --> 00:01:13,030

intense thunderstorms.

19

00:01:13,030 --> 00:01:17,000

20

00:01:17,000 --> 00:01:21,000

Strong winds formed by these storms can overshoot the troposphere and reach

21

00:01:21,000 --> 00:01:25,000

higher in Earth’s atmosphere, injecting pollutants into the stratosphere,

22

00:01:25,000 --> 00:01:29,000

which can affect the ozone layer. Using an ER-2 plane flying

23

00:01:29,000 --> 00:01:33,030

up to 70,000 feet, the Dynamics and Chemistry of the Summer Stratosphere,

24

00:01:33,030 --> 00:01:37,000

or DCOTSS, mission will investigate how the pollutants

25

00:01:37,000 --> 00:01:41,030

reach the stratosphere and how their impact could change in the future.

26

00:01:41,030 --> 00:01:45,030

27

00:01:45,030 --> 00:01:49,030

28

00:01:49,030 --> 00:01:53,030

Farther south, the Mississippi River Delta is

29

00:01:53,030 --> 00:01:57,030

sinking as sea levels continue to rise globally.

30

00:01:57,030 --> 00:02:01,030

31

00:02:01,030 --> 00:02:05,000

The Delta-X mission (no acronyms here)

32

00:02:05,000 --> 00:02:09,030

will combine measurements from two planes – a King Air and a Gulfstream –

33

00:02:09,030 --> 00:02:13,000

with measurements taken on the ground and in the water to study

34

00:02:13,000 --> 00:02:17,030

how and where soil is naturally transported and deposited by water.

35

00:02:17,030 --> 00:02:21,030

36

00:02:21,030 --> 00:02:25,000

37

00:02:25,000 --> 00:02:29,030

This can help researchers better understand how the coastal regions will be affected by

38

00:02:29,030 --> 00:02:33,030

rising sea levels.

39

00:02:33,030 --> 00:02:37,030

40

00:02:37,030 --> 00:02:41,030

41

00:02:41,030 --> 00:02:45,000

42

00:02:45,000 --> 00:02:49,000

On the East Coast of the United States,

43

00:02:49,000 --> 00:02:53,000

the Aerosol Cloud Meteorology Interactions Over the Western Atlantic Experiment,

44

00:02:53,000 --> 00:02:57,030

or ACTIVATE, mission will look at how clouds in the marine boundary layer –

45

00:02:57,030 --> 00:03:01,030

roughly the 2 kilometers above the ocean – affect the water cycle.

46

00:03:01,030 --> 00:03:05,030

These cloud systems cover large stretches of the ocean

47

00:03:05,030 --> 00:03:09,000

and are not well-represented in climate models.

48

00:03:09,000 --> 00:03:13,000

ACTIVATE will use two planes – a Falcon and a King Air – to take measurements

49

00:03:13,000 --> 00:03:17,030

remotely and in situ, including releasing dropsondes through the clouds.

50

00:03:17,030 --> 00:03:21,030

51

00:03:21,030 --> 00:03:25,030

52

00:03:25,030 --> 00:03:29,000

Flying the same corridor,

53

00:03:29,000 --> 00:03:33,000

the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms,

54

00:03:33,000 --> 00:03:37,030

or IMPACTS, mission will use measurements

55

00:03:37,030 --> 00:03:41,000

on the ground, scientific balloons and two planes –

56

00:03:41,000 --> 00:03:45,000

the ER-2 and the P-3 – to measure snowstorms at all altitudes.

57

00:03:45,000 --> 00:03:49,030

IMPACTS is looking closely

58

00:03:49,030 --> 00:03:53,030

at the intense bands of snow that form inside clouds to improve forecasting

59

00:03:53,030 --> 00:03:57,030

of snowstorms in the future.

60

00:03:57,030 --> 00:04:01,030

61

00:04:01,030 --> 00:04:05,000

62

00:04:05,000 --> 00:04:09,000

63

00:04:09,000 --> 00:04:22,095
