 Hello, this is Professor Steven Esheba of the University of Puget Sound, and I'm here to help you out with navigating the ESRL NOAA site for looking at ice and snow data. So this is the website that you want to go to, and I've already put that into my Firefox browser. So here we are at the ISOA website. It's kind of a clearinghouse for Arctic Observations, and if you want to learn more about it, you can go to this mission statement and learn about that and But where I want to take you to is this Observation observatories tour, and so if you go there you can see there's all these different stations Here are the institutions that sponsor those stations. So for example NSF sponsors the Summit Greenland site and So and here's all the different regions of the Arctic that that have station data. We are going to go to this pick up data, so I'm going to go to data, data at a glance and Here's a table that shows you where how you can pick up the data itself. We're going to be interested in Summit Greenland so that's this column here and You can kind of see that it the column labels here So you'll know that you stay on the same column, but we don't want to go down to Radiometric and in particular we want long wave spectral Okay, and so As it turns out we want this first entry here. So just say take me to the data and Now the kind of data set that we are looking for is Well, it's all these are the same data, but I want a particular Data file which it corresponds to the year 2010 December 28th, and so what you will do is click on that data right there that file and you want to save this to your computer
