WEBVTT FILE 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
