Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A ceiling balloon is used by meteorologists to determine the height of the base of clouds above ground level during daylight hours. The principle behind the ceiling balloon is a balloon with a known ascent rate (how fast it climbs) and determining how long the balloon rises until it disappears into the cloud. Ascent rates yield the ceiling height.
