WEBVTT FILE 1 00:00:00.020 --> 00:00:04.020 [slate] 2 00:00:04.040 --> 00:00:08.030 [slate] 3 00:00:08.050 --> 00:00:12.140 So the GLOBE Observer 4 00:00:12.160 --> 00:00:16.240 app is a free citizen science app available in Google play and 5 00:00:16.260 --> 00:00:20.390 on the Apple store. And what it does is it walks you through doing data collection. 6 00:00:20.410 --> 00:00:24.580 So we have clouds, for the eclipse we're using clouds where it 7 00:00:24.600 --> 00:00:28.690 will ask you what type of cloud you see, how much of the sky is covered by clouds. 8 00:00:28.710 --> 00:00:32.780 And we're also adding air temperature where you just use a simple thermometer and 9 00:00:32.800 --> 00:00:36.930 you measure how much the air temperature is changing during the eclipse. 10 00:00:36.950 --> 00:00:40.960 [slate] 11 00:00:40.980 --> 00:00:45.140 So the first thing to do is to 12 00:00:45.160 --> 00:00:49.220 download the free GLOBE Observer app which is available on Google play and 13 00:00:49.240 --> 00:00:53.310 on the IOS Apple store. And so you do need 14 00:00:53.330 --> 00:00:57.420 to register that. Just we need an email to send you a password. And that you can 15 00:00:57.440 --> 00:01:01.580 do cloud observations just with that. If you want to do air temperature 16 00:01:01.600 --> 00:01:05.620 then the next thing you need is just some kind of really simple thermometer. It can be 17 00:01:05.640 --> 00:01:09.710 a liquid filled thermometer like one of these. Or it can be a digital thermometer 18 00:01:09.730 --> 00:01:13.820 if you have like a thermometer for your patio. Ideally you want something that's 19 00:01:13.840 --> 00:01:17.980 to measure weather and air temperature. And then all you need to do is 20 00:01:18.000 --> 00:01:22.040 on the day of the eclipse go into the app and it'll remind you when to 21 00:01:22.060 --> 00:01:26.110 make observations. It'll actually get your location so it'll know when you're point of maximum 22 00:01:26.130 --> 00:01:30.230 eclipse is and give you reminder about when to make measurements. We actually also 23 00:01:30.250 --> 00:01:34.400 encourage people. You can start doing cloud observations now. So you can go practice 24 00:01:34.420 --> 00:01:38.450 your cloud observations today and get familiar with how that part of the 25 00:01:38.470 --> 00:01:42.550 app works. And then temperature measurements will start being available August 18th. 26 00:01:42.570 --> 00:01:46.640 So you can even take measurements a few days before to make sure you know how to 27 00:01:46.660 --> 00:01:50.780 all the buttons works. And how the app walks you through the steps. 28 00:01:50.800 --> 00:01:54.850 [slate] 29 00:01:54.870 --> 00:01:58.970 Well so the data is going into 30 00:01:58.990 --> 00:02:03.130 GLOBE program database which is a very long standing student citizen 31 00:02:03.150 --> 00:02:07.160 science project having teachers and students collect data together. So that data 32 00:02:07.180 --> 00:02:11.220 is available there for those students to do projects. We have some NASA 33 00:02:11.240 --> 00:02:15.350 researchers at NASA Goddard who are going to take a look. And if we get enough data 34 00:02:15.370 --> 00:02:19.490 it's distributed well and if it's good quality then they will also 35 00:02:19.510 --> 00:02:23.540 consider looking at that for their research. But I also think it's important that you 36 00:02:23.560 --> 00:02:27.630 citizen scientists themselves, if you're contributing data or even if you're not 37 00:02:27.650 --> 00:02:31.720 you can go in and you can actually check out what other people have observed 38 00:02:31.740 --> 00:02:35.870 the observations that have been made in other parts of the country 39 00:02:35.890 --> 00:02:39.950 and look for your own patterns within the data. 40 00:02:39.970 --> 00:02:44.070 [second SOT about data] The reason we want to collect this 41 00:02:44.090 --> 00:02:48.230 data is because the Earth systems are all interconnected. If the sun's light 42 00:02:48.250 --> 00:02:52.300 stops for this short period of time it's going to effect 43 00:02:52.320 --> 00:02:56.400 clouds and temperature that then interact with other systems in the Earth. And we can 44 00:02:56.420 --> 00:03:00.520 use the information about the changes that happen to look at weather modeling 45 00:03:00.540 --> 00:03:04.680 and climate modeling and all sorts of research that's being done to 46 00:03:04.700 --> 00:03:08.730 into how these processes are changing over time. 47 00:03:08.750 --> 00:03:12.740 [slate] 48 00:03:12.760 --> 00:03:16.850 Well so the truth is that NASA we can't be everywhere 49 00:03:16.870 --> 00:03:20.950 and by recruiting all these citizen scientists to help collect data 50 00:03:20.970 --> 00:03:25.130 we're getting data from places we would not be able to get it otherwise. 51 00:03:25.150 --> 00:03:29.270 There is no way that we would collect data across the entire 52 00:03:29.290 --> 00:03:33.340 country without having the help of people downloading the app and 53 00:03:33.360 --> 00:03:37.450 collecting the data. And i do also think it makes people more aware of what's happening 54 00:03:37.470 --> 00:03:41.630 around them. Once you start observing clouds you'll start to see how quickly 55 00:03:41.650 --> 00:03:45.740 they change and how interesting they can be. So I think there's a benefit for observers 56 00:03:45.760 --> 00:03:49.840 as well. They're contributing to the database but they're also increasing their awareness 57 00:03:49.860 --> 00:03:53.960 of what's actually in the environment around them and that's very important too. For 58 00:03:53.980 --> 00:03:58.100 that eight year old but also for adults as well. 59 00:03:58.120 --> 00:04:02.180 [Second SOT about participation] Well the first reason to participate 60 00:04:02.200 --> 00:04:06.300 is just because it's fun. Using the app will make you see clouds in a new way. 61 00:04:06.320 --> 00:04:10.510 You'll start to observe how quickly they change and what types of clouds you're 62 00:04:10.530 --> 00:04:14.560 seeing in the sky. And during the eclipse I think it will make you more 63 00:04:14.580 --> 00:04:18.640 aware of some of the other things that are happening like the air temperature dropping. 64 00:04:18.660 --> 00:04:22.780 But the other reason we really need your participation is the fact that we cannot 65 00:04:22.800 --> 00:04:26.980 be everywhere collecting data ourselves. And so you can really 66 00:04:27.000 --> 00:04:31.040 be helpful to us by providing this really broad range of data 67 00:04:31.060 --> 00:04:35.120 everywhere from totality to partial eclipse and putting that 68 00:04:35.140 --> 00:04:39.250 into a database that we can access. The data will go into 69 00:04:39.270 --> 00:04:43.430 the GLOBE database which is a longstanding citizen science project that's been 70 00:04:43.450 --> 00:04:47.520 going for more than 20 years having teachers and students collect data so that 71 00:04:47.540 --> 00:04:51.640 data will not only go into a database that's accessible to NASA scientists 72 00:04:51.660 --> 00:04:55.780 as well as the citizen scientists themselves, but also that students 73 00:04:55.800 --> 00:04:59.970 use for their own research projects. So you're also supporting student 74 00:04:59.990 --> 00:05:04.050 involvement in science and engineering and math. 75 00:05:04.070 --> 00:05:08.070 [slate] 76 00:05:08.090 --> 00:05:12.270 Well I do want to make a 77 00:05:12.290 --> 00:05:16.300 quick note about safety. Although you don't need to look at the sun at all 78 00:05:16.320 --> 00:05:20.370 during GLOBE Observer observations, you just need your thermometer and your 79 00:05:20.390 --> 00:05:24.490 looking at the clouds. It is very important that if you are going to try and look at the sun directly 80 00:05:24.510 --> 00:05:28.630 that you make sure you have safe viewing glasses. There are ways to 81 00:05:28.650 --> 00:05:32.690 look with a pinhole projection or use something like one of these 82 00:05:32.710 --> 00:05:36.740 3D printed pinhole projectors if you want to look at the sun indirectly 83 00:05:36.760 --> 00:05:40.840 or observe the eclipse indirectly. But make sure that if you are 84 00:05:40.860 --> 00:05:44.980 looking at the sun that you do not do it without your safe viewing glasses. 85 00:05:45.000 --> 00:05:49.140 [second SOT about safety] So you don't need 86 00:05:49.160 --> 00:05:53.200 to look at the sun at all to do the cloud observations, to do the temperature observations 87 00:05:53.220 --> 00:05:57.260 But anytime except during that brief period of totality 88 00:05:57.280 --> 00:06:01.350 if you do want to look at the sun make sure you have your safe viewing glasses. That's really 89 00:06:01.370 --> 00:06:05.470 important. You do not want to damage your eyes by looking at the sun. 90 00:06:05.490 --> 00:06:10.160 Now if you don't have those viewing glasses there's a lot of different 91 00:06:10.180 --> 00:06:14.310 still observe the eclipse and basically project an image of the sun 92 00:06:14.330 --> 00:06:18.370 that you will see the moon 93 00:06:18.390 --> 00:06:22.430 eating away at it. So on the NASA eclipse website 94 00:06:22.450 --> 00:06:26.510 eclipse2017.nasa.gov there's lot of different ways to be able to view the eclipse 95 00:06:26.530 --> 00:06:30.650 including something like this. This is just a 3D printed pinhole camera that you can use to 96 00:06:30.670 --> 00:06:34.880 project the sun. So do make sure you are safe when viewing the eclipse. 97 00:06:34.900 --> 00:06:38.920 [slate] 98 00:06:38.940 --> 00:06:43.080 Absolutely we want data from everywhere 99 00:06:43.100 --> 00:06:47.250 on the path of totality and off the path of totality. Because even if you're not 100 00:06:47.270 --> 00:06:51.310 in those two and two and a half minutes of seeing the corona, the sun is still 101 00:06:51.330 --> 00:06:55.390 blocked. there is still reduced energy reaching the Earth's surface even 102 00:06:55.410 --> 00:06:59.510 in the areas of partial eclipse. And that should, we should be able to 103 00:06:59.530 --> 00:07:03.690 see some effects on temperature and clouds because of that drop in energy. 104 00:07:03.710 --> 00:07:07.780 reaching the Earth's surface. [Second SOT] We absolutely 105 00:07:07.800 --> 00:07:11.870 need observers both from the path of totality and off the path of totality. 106 00:07:11.890 --> 00:07:15.990 Even though you're not seeing that for that two and a half 107 00:07:16.010 --> 00:07:20.160 minutes of full darkness if you're in a partial eclipse area. The sun 108 00:07:20.180 --> 00:07:24.230 light is still being diminished for the period of the eclipse. So there's 109 00:07:24.250 --> 00:07:28.340 should be an effect on temperature, less than if you're on totality 110 00:07:28.360 --> 00:07:32.470 because there's less blocking overall, but you will still see an impact 111 00:07:32.490 --> 00:07:36.660 if you are not under the total eclipse path. 112 00:07:36.680 --> 00:07:40.700 [slate] 113 00:07:40.720 --> 00:07:44.780 Well I just 114 00:07:44.800 --> 00:07:48.850 have to say I'm really excited for everybody to be participating in this project 115 00:07:48.870 --> 00:07:52.950 We could not do it without the help of the citizen scientists across the country 116 00:07:52.970 --> 00:07:56.960 helping us collect data and we really appreciate it. 117 00:07:56.980 --> 00:08:00.990 [slate] 118 00:08:01.010 --> 00:08:05.180 So the eclipse offers a really unique natural 119 00:08:05.200 --> 00:08:09.320 experiment. A lot of the processes on Earth are affected by 120 00:08:09.340 --> 00:08:13.390 sunlight. Things like cloud formation, evaporation, all of those sort of things are 121 00:08:13.410 --> 00:08:17.460 affected by sunlight. So during the eclipse we have a unique to take 122 00:08:17.480 --> 00:08:21.570 data when the sun is blocked, and when we're not getting that sunlight 123 00:08:21.590 --> 00:08:25.720 for a period of time. But NASA scientists can't be everywhere we need to be 124 00:08:25.740 --> 00:08:29.730 to collect really comprehensive data. So that's where we need the help of citizen scientist 125 00:08:29.750 --> 00:08:33.800 who are distributed all across the country, whether they're in totality 126 00:08:33.820 --> 00:08:37.890 or not in totality, collecting data about what's happening with the clouds and the air temperature 127 00:08:37.910 --> 00:08:40.934 during this really neat event.
