The layer of the atmosphere closest to Earth's surface is the troposphere. It's the lowest layer and extends from the Earth's surface up to an average height of about 7 to 20 kilometers (4 to 12 miles) above sea level, although its height can vary depending on the region and weather conditions. The troposphere is where most weather phenomena occur, and it contains the air we breathe and the majority of Earth's clouds and weather systems.

You must be 20° above (north) the equator
Parts in the eastern side are 15 feet above sea level. Parts in the western side are 20 feet above sea level. 15' = evacuation C 20' = evacuation D
