Atmospheric sampling networks keep track of the gases in the troposphere, the layer of Earth’s atmosphere near the surface, as they vary in time and space; space- based sounders are providing continuous measurements of some gases from satellites Ocean sampling networks are reaching similar levels of coverage Our capacity to manage large quantities of data has grown enormously Earth systems models are getting more sophisticated

The figure shows concentrations of carbon dioxide at the Mauna Loa Observatory, Hawaii (Latitude 19 N) over a ten-year period. Draw the comparable patterns for Barrow, Alaska (Latitude 71 N) and the South Pole (Latitude 90 S) on these same axes. It’s not important to get the values right, of course – but do your best to show how they compare to Mauna Loa, in position and magnitude.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
