1
00:00:00,030 --> 00:00:03,959
all right good evening everybody thank
you all for coming to the NASA hyperwall

2
00:00:03,959 --> 00:00:07,290
I know it's not just all about the books
right everybody's here to learn

3
00:00:07,290 --> 00:00:12,179
something, so thank you for sitting and
listening to this I'm just here to give

4
00:00:12,179 --> 00:00:16,049
an overview of what we do at our science
at NASA and a lot of people don't know

5
00:00:16,049 --> 00:00:21,060
that NASA has an earth science division
and what we do is, next slide please,

6
00:00:21,060 --> 00:00:25,529
we use the unique vantage point of space
currently our 23 Earth observing

7
00:00:25,529 --> 00:00:30,689
satellites to look at different
properties of our global world some of

8
00:00:30,689 --> 00:00:34,770
these are focused on the biosphere some
of these are focused on the cryosphere

9
00:00:34,770 --> 00:00:39,390
and we can study many aspects of the
Earth's system and at NASA we use this

10
00:00:39,390 --> 00:00:43,800
information to explore and that
exploration leads to discovery which

11
00:00:43,800 --> 00:00:48,329
leads to research so our overarching
goal is to understand and protect our

12
00:00:48,329 --> 00:00:56,129
home planet for societal benefit, next
slide, so I just want to give you an

13
00:00:56,129 --> 00:01:00,510
overview since our science at NASA is
about to turn 50 we started to talk

14
00:01:00,510 --> 00:01:04,830
about some of the major highlights of
our findings both basic and applied

15
00:01:04,830 --> 00:01:09,689
research over the years, um, and what we
realized in doing this is that some of

16
00:01:09,689 --> 00:01:13,229
what we do some of the images we're able
to project some of the predictions were

17
00:01:13,229 --> 00:01:18,330
able to make with models actually looks
somewhat like artwork, so we can do

18
00:01:18,330 --> 00:01:23,400
things like make basic research
observations of aerosols and different

19
00:01:23,400 --> 00:01:27,420
types of aerosols and use them and feed
them into climate and weather prediction

20
00:01:27,420 --> 00:01:31,740
and that's what you're seeing here so
this is a simulation of aerosols during

21
00:01:31,740 --> 00:01:36,240
the 2017 hurricane season, you can see a
number of different aerosols on the

22
00:01:36,240 --> 00:01:42,869
bottom you could also track the
Hurricanes by name, next slide, and so one

23
00:01:42,869 --> 00:01:46,799
of the most iconic stories I think to
come out of NASA mat of science in

24
00:01:46,799 --> 00:01:51,869
general was actually detailing the hole
in the ozone layer in the 70s and how

25
00:01:51,869 --> 00:01:56,610
this led to things like the Montreal
Protocol and actually led to it doing

26
00:01:56,610 --> 00:02:00,720
things like monitoring the progress of
the recovery of the whole in the

27
00:02:00,720 --> 00:02:04,380
ozone layer it is very important for
shielding Earth from a lot of harmful

28
00:02:04,380 --> 00:02:09,599
radiation and how the effect of the
Montreal Protocol led to its recovery

29
00:02:09,599 --> 00:02:12,370
over time and it's been relatively
stable since the

30
00:02:12,370 --> 00:02:16,870
1990s but I think satellite data are
absolutely critical in getting that

31
00:02:16,870 --> 00:02:20,620
global observation and when coupled with
in situ observations no matter what

32
00:02:20,620 --> 00:02:24,940
aspect of the Earth System properties
were looking at it's very important for

33
00:02:24,940 --> 00:02:28,920
giving us motion forward scientifically,
next slide

34
00:02:31,060 --> 00:02:32,500
so one of the other I think

35
00:02:32,500 --> 00:02:36,970
truly iconic animations and something
were able to detail over time is looking

36
00:02:36,970 --> 00:02:43,180
at changes in ice cover at the poles and
this shows you the annual Arctic sea ice

37
00:02:43,180 --> 00:02:48,430
minimum starting in 1979 with the graph
that overlays and shows the big drops

38
00:02:48,430 --> 00:02:54,250
over the last ten years and so to be
able to track this change over time

39
00:02:54,250 --> 00:03:00,310
allows us to not only explore spatially
but temporally rate so what we're able

40
00:03:00,310 --> 00:03:06,120
to do is identify changes and long term
trends in our climate, next slide

41
00:03:08,600 --> 00:03:09,660
Thanks

42
00:03:09,670 --> 00:03:15,790
so the other animation I like to show is
20 years of Earth's biosphere now if you

43
00:03:15,790 --> 00:03:21,609
know anything about biology on the earth
it supports a tremendous economy

44
00:03:21,609 --> 00:03:26,919
worldwide both on land and in the ocean
and what I like about this animation is

45
00:03:26,919 --> 00:03:32,019
it's like watching the Earth breathe,
okay, you can actually see many changes

46
00:03:32,019 --> 00:03:35,560
over time and in addition you can
actually understand the impacts of

47
00:03:35,560 --> 00:03:40,780
atmospheric phenomenon on our land and
on our oceans, next slide

48
00:03:41,900 --> 00:03:43,860
so one of the

49
00:03:43,860 --> 00:03:47,620
other pieces that's very important and
in 10 minutes I don't have enough time

50
00:03:47,620 --> 00:03:51,700
to show you all of what we do at NASA
but taking this time series of

51
00:03:51,700 --> 00:03:55,030
information, all of this spatial 
information, all of the temporal

52
00:03:55,030 --> 00:03:58,800
information and actually using it for a
predictive capability is really

53
00:03:58,810 --> 00:04:04,690
important and so this is a GEOS-5 model
run different properties shown in each

54
00:04:04,690 --> 00:04:08,919
panel and it can be used to look at
changes in the atmosphere and those

55
00:04:08,919 --> 00:04:12,220
impacts of the changes in the atmosphere
on the rest of the Earth system over

56
00:04:12,220 --> 00:04:18,430
time and this is a constantly evolving
animation because we initialize the

57
00:04:18,430 --> 00:04:22,220
models with actual data and then can use
some of it to do hind

58
00:04:22,220 --> 00:04:25,400
casting and forecasting, next slide

59
00:04:26,300 --> 00:04:30,020
so the
only thing that's I think what's really

60
00:04:30,020 --> 00:04:34,370
unique at NASA is not only having the
research programs embedded with some of

61
00:04:34,370 --> 00:04:39,290
the satellite information but we also do
Applied Sciences okay and that means we

62
00:04:39,290 --> 00:04:43,610
take all of our research findings all of
our research data products and try to

63
00:04:43,610 --> 00:04:48,470
transition them into the hands of
managers conservationists and you listen

64
00:04:48,470 --> 00:04:52,610
very closely to see if there's something
that they need that they're not getting

65
00:04:52,610 --> 00:04:57,920
that we can actually produce and so one
of the things that I think is important

66
00:04:57,920 --> 00:05:03,170
to look at over time is not only the
coverage and recovery of things like

67
00:05:03,170 --> 00:05:08,150
fires and this is Yellowstone but
actually looking at the lasting effects

68
00:05:08,150 --> 00:05:12,380
of things like wildfires and actually
feeding that information forward to

69
00:05:12,380 --> 00:05:17,690
firefighters as things are going on, so
this is the burn recovery in Yellowstone

70
00:05:17,690 --> 00:05:24,169
and you can really see how some of the
fires caused scars that take a long time

71
00:05:24,169 --> 00:05:27,880
to recover if at all next slide

72
00:05:32,500 --> 00:05:38,960
thank you so one of the other things I
thought was really unique to show was

73
00:05:38,960 --> 00:05:43,490
some of you may remember in 2018 and why
there were a number of volcanic

74
00:05:43,490 --> 00:05:48,440
eruptions for a good chunk of the year
and so what you're seeing right now is

75
00:05:48,440 --> 00:05:53,510
sort of the before picture before the
Kilauea eruptions of 2018 and then

76
00:05:53,510 --> 00:05:57,380
you'll see some thermal imagery that
shows you the actual eruptions and then

77
00:05:57,380 --> 00:06:00,740
you'll see another LandSat shot that
shows you what the area looked like

78
00:06:00,740 --> 00:06:05,540
after, we can feed this information
forward to managers on the ground and

79
00:06:05,540 --> 00:06:09,590
policymakers it can be very helpful and
they're planning for the future and

80
00:06:09,590 --> 00:06:14,990
their recovery, so while we don't really
do any management or policymaking at

81
00:06:14,990 --> 00:06:18,470
NASA a lot of what we do is policy
relevant and we're constantly looking

82
00:06:18,470 --> 00:06:26,690
for those synergies, next slide, okay and
so I love this one this is actually GPM

83
00:06:26,690 --> 00:06:31,880
data and I remember one day this summer
there was a horrific day of rainstorms

84
00:06:31,880 --> 00:06:37,280
in Washington and it just so happens
that GPM was passing over and we were

85
00:06:37,280 --> 00:06:41,660
able to catch her capture in the
Washington DC region this horrible

86
00:06:41,660 --> 00:06:45,500
deluge of rain that left us with like
four inches of rain in one day

87
00:06:45,500 --> 00:06:53,150
and so Gail Skofronik-Jackson the GPM
program scientist said you know we

88
00:06:53,150 --> 00:06:57,500
happen to catch this and she said this
one forward and I think Thomas Zurbuchen

89
00:06:57,500 --> 00:07:00,800
but--can tweeted it out that day and we
just thought it was what a what a chain

90
00:07:00,800 --> 00:07:04,610
of events to actually capture the local
real rainstorm and get a picture of it

91
00:07:04,610 --> 00:07:07,520
from one of our Earth observing
satellites and of course one of the

92
00:07:07,520 --> 00:07:11,140
things that NASA does is feed a lot of
this information into weather prediction

93
00:07:11,180 --> 00:07:12,160
next slide,

94
00:07:13,500 --> 00:07:19,460
okay so it's your planet
right, we're turning 50 it's one of those

95
00:07:19,460 --> 00:07:23,150
things that you say well there are a lot
of things that we could still do and

96
00:07:23,150 --> 00:07:26,720
we're always thinking about that we have
a lot of new missions and formulation

97
00:07:26,720 --> 00:07:30,140
and a lot in development and I know
around the corner a lot of you have

98
00:07:30,140 --> 00:07:36,770
queued up, next slide, for what's what we
call our new Earth at Night book and just

99
00:07:36,770 --> 00:07:41,270
because the earth is dark doesn't mean
there aren't things going on that we can

100
00:07:41,270 --> 00:07:44,480
measure and understand
we've actually used this nightlights

101
00:07:44,480 --> 00:07:49,160
product and fed this information forward
not for just managing recovery from

102
00:07:49,160 --> 00:07:53,270
natural disasters but also doing things
like tracking illegal unreported and

103
00:07:53,270 --> 00:07:58,040
unregulated fishing so these images even
at night when things look serene and

104
00:07:58,040 --> 00:08:02,990
very quiet can be very useful for our
science, so with that I will say thank

105
00:08:02,990 --> 00:08:09,100
you I hope you all stay here and learn
something more about Earth science at NASA
