Technological advances in the twentieth century have enabled scientists to undertake research on virtually every location on the Earth. Parallel advances in space technology have provided a rapidly increasing number of satellite platforms that can be used to study complex physical processes in the Earth-atmosphere system. Remote sensing is the small or large-scale acquisition of information of an object or phenomenon in a given area by the use of recording devices that are not in physical contact with the object or area of interest, such as aircraft or satellite. The basis of remote sensing is the electromagnetic spectrum. Satellite remote sensing often permits real time, year round and long-term study. Remote sensing has greatly improved mass balance estimates of ice sheets and glaciers in Antarctica. Mass balance is the difference between accumulation and ablation of mass on an ice sheet or glacier over a time period. There are three ways to measure the mass balance of an ice sheet: the mass-budget method, the volume method, and the geodetic method.
