CEOS EO HANDBOOK � MEASUREMENTS
Earth observation satellites provide important data about the Earth and its environment, helping develop our understanding of the basic Earth System and human influences on it. These data cover measurements of a very wide range of geophysical parameters, spanning the whole spectrum of the environment � atmosphere, land, oceans, ice and snow. You can read more about these measurements in the Earth Observation Handbook .

The CEOS Missions, Instruments, and Measurements database contains information on many key measurements of interest to the main user groups of Earth observation satellite data. The table below includes links to further information on broader measurement categories (left), more detailed measurements (centre), and measurement timelines (right).
