Program Description: Starting with temperature records collected over 100 years ago, Measuring the Earth's Temperature takes the viewer from the earliest weather stations and balloon launches, to a network of super weather stations constructed in the 21st century. Highlights include showing how weather balloon launches work, the anatomy of a weather station, and how weather data, using computers, is transformed into long and short term weather forecasts. This very same data is also used to graph yearly temperature changes across the planet.
