What are EOS Satellites designed to observe?

EOS (Earth Observing System) satellites are specifically designed to provide comprehensive observations of a variety of components in the Earth's system. Their primary purpose is to collect data on the Earth's land, atmosphere, biosphere, and hydrosphere, which allows scientists to monitor changes and understand the interactions between different environmental processes.

These satellites gather critical information on vegetation, land use, air quality, ocean temperatures, and many other factors. This multifaceted approach enables researchers to study phenomena such as climate change, natural disasters, and resource management with a holistic perspective. By focusing on all these different aspects of the Earth, EOS satellites play a vital role in advancing our understanding of the planet and helping to inform policy and conservation efforts.

The other choices do not encompass the full scope of what EOS satellites are intended to observe. For instance, focusing only on the Earth's atmosphere would overlook vital data from other components. Similarly, limiting observations to solar systems or only Antarctic regions would significantly restrict the potential benefits and applications of the data collected by these satellites.
