Problem 1 - Solutions

These answers have been calculated with a hand calculator, using the constant values from the notes, but should be good to 4 or 5 significant figures. If you differ significantly [more than 10%], you definitely have code errors. Also, it is worth noting that there is a typo is the Brasseur and Solomon Table from the Standard Atmosphere: 1976. They have 2.3 mb for 40 km and it should be 2.8 mb.
