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.
