Satellite Observations
Satellite-based sensing and imaging technologies cannot record the impact that climate change has on a people's way of life, but they can provide a numerical understanding of what is happening in an area being studied. We call data that are collected by instruments and can be compared mathematically quantitative data.

Earth System: Satellites
Satellite observations can comprise data from multiple readings, giving scientists the ability to make broad evaluations—for example, gauging the impact of climate change over time throughout the entire Arctic region.
In the next part of this activity, you will be working with visualizations made from satellite data. As a class, begin by watching the Earth System: Satellites Video. Then, discuss the following questions:
- In what ways do satellites affect your life?
- What kinds of data do scientists gather via satellite?
