Problem 1 - The Aura satellite is designed to study the composition of Earth's atmosphere, and produces 31,755 DVDs-worth of data every year. How much data does it produce in one day? A standard, single-layer, recordable DVD has 4.7 GB of storage space. ( 2 points) Problem II - The Aura satellite orbits Earth 360 orbits in 25 days. How many full orbits does it complete in one day? (2 points) Problem III - Ozone is a molecule that forms high up in Earth's atmosphere and blocks harmful ultraviolet light from reaching the ground. In 2011, the Aura spacecraft detected 17,052,000 tons of ozone destroyed over the Arctic Region during a 1-week period of time. How much ozone was lost in a single hour during this one week? (2 points) Problem IV If the diameter of Earth is 12,700 km, about what is the approximate rectangular area of the Arctic ozone hole interior to the white oval contour shown in the above satellite imagery in units of millions of square kilometers? (Hint: Measure your rectangle where the maximum volume of the rectangle is within the white oval contour. (3 points) Problem V The study by Dr. Gloria Manney and her colleagues, which was published in the journal Nature on October 2, 2011, stated that the loss of ozone was most severe between altitudes of 16 to 22 kilometers. What is the total volume of the ozone layer involved in the Arctic depletion in 2011 in millions of cubic kilometers? ( 3 points) Problem VI The normal Arctic concentration of ozone is about 4 parts per million by volume (ppmV), but during the Arctic depletion it fell to 1.5 ppmV.
