00:00:01.030 --> 00:00:05.000
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
Stay tuned for more as these five missions take off!
