 Hello, this is Professor Stephen Nesheben. I'm here to help you out with the recovering some temperature data from a NOAA website. And if you go from Moodle here, here's the link to the NOAA website, and that's what you'll want to do. And it's the Earth System Research Laboratory Global Monitoring Division, and you'll kind of see how this works. We want meteorology, so I'm going to click on that filter element. And what we're going to focus on for this this exercise is minute averages, so I'm clicking on that. Now these are all these different sites. There's Barrow, there's South Pole, there's American Samoa, and just you'll get to choose which one you want, but for now I'm going to go ahead and choose the Barrow data. And so now we're going to be looking at minute by minute averages at Barrow, and what we'll want to do is choose one of these data sets from a while ago. So I'm going to just look at 1990, that seems like a long enough time ago. And in this case I'll go ahead and choose, let's say January data. And so I've done that, and now I'm going to right click on this and what I need to do is save this to to my own to my laptop. And so I'm going to do that. And once we're done with that, then what we're going to want to do is open this up in Google Sheets. So I've already got a link to Google Sheets. And I'm going to say, okay, I want a new spreadsheet. So I clicked on that blank guy there. Now because these files are deliminated by spaces, what we're going to have to do, the columns are separated by spaces. We have to do what's called an import. So I'm going to do an upload there, select the file from my device. And so there's that one minute resolution data. And hopefully this will work for you. I'm just going to take all those defaults and say import all that data. And if it worked, then you'll see in column K a bunch of numbers that look like temperatures in Celsius, which seems to have done okay. So I'm going to click that column heading. And what we want to do is go to, I'm going to insert a chart. So that's what I'm doing right there. And hopefully it'll come up here in just a minute. And it defaults to a line chart. But what we really want is what we call this histogram. So I'm going to do that. And well, and there we go. Now in some cases, you might be picking up a crazy range way off to minus a thousand or something like that. If that happens, what we need to do, what you're going to need to do is do what's called customize. And so for example, here on the histogram, well, regardless, the bucket size defaulted to some value. But I think a degree or one or two degrees is get you better statistics. And what else do we want to do? Oh, I mentioned that we want might want to change the horizontal axis. So the minimum, let's say I want to be minus 50. And the maximum I want to be whatever, you know, well, actually, I'd like minus 40 a little bit better. So I'll do it that way. And you can set the maximum. When you go to compare two different years, you're going to want to have that bucket size and the range of temperatures the same for the two different years. What I also like to do is move this chart to its own sheet. So it's kind of got its own default size. Let's see. Oh, so just so you can keep track of things, we do want to put some titles on this. So in this case, this is this is going to be 1990, Barrow January temperatures. So you can keep track of that. And well, that's about that's about it. You're going to want to choose a different time period and do this again and make sure that the ranges are all the same. So you could maybe compare some climate changes over the course of that time interval.
