Hyperspectral. Hyperspectral measurements
 allow us to look beyond what human eyes

2
00:00:03,833 --> 00:00:07,300
can see to peer through cosmic dust clouds
 or monitor the health of our ocean.

3
00:00:07,766 --> 00:00:11,100
Electromagnetic energy travels in waves
 that we perceive in different ways

4
00:00:11,100 --> 00:00:13,600
-- from very long
 radio waves to very short

5
00:00:13,600 --> 00:00:16,500
X- and gamma ray waves with visible light
 somewhere in the middle.

6
00:00:16,800 --> 00:00:18,500
Hyperspectral analysis combines 

7
00:00:18,500 --> 00:00:21,433
measurements taken over a wide range
 of that electromagnetic spectrum.

00:00:21,833 --> 00:00:24,500
The upcoming Plankton
 Aerosol Cloud ocean Ecosystem

9
00:00:24,500 --> 00:00:27,766
satellite -- PACE -- will help us study
 Earth's ocean in new ways,

10
00:00:27,900 --> 00:00:30,800
using hyperspectral measurements of light
 emitted from Earth's surface.

11
00:00:30,800 --> 00:00:31,866
Using ultraviolet 

12
00:00:31,866 --> 00:00:34,900
light, we'll see tiny particles
 suspended in our ocean and atmosphere,

13
00:00:35,066 --> 00:00:37,733
which helps us understand the impact
 of human activities on our planet.

14
00:00:38,300 --> 00:00:41,800
Meanwhile, measurements in visible light
 -- what our eyes see -- help us monitor

15
00:00:41,800 --> 00:00:43,500
the concentration of phytoplankton, 

16
00:00:43,500 --> 00:00:46,266
tiny organisms that make up the base
 of the ocean food web.

17
00:00:46,500 --> 00:00:49,100
Using even longer
 infrared measurements will allow space

18
00:00:49,100 --> 00:00:52,000
to monitor atmospheric conditions
 above and near the ocean.

19
00:00:52,200 --> 00:00:55,533
Bring all these data together and we'll
 have a very full picture of Earth's ocean.
