Scientists collect data to understand Earth and how it changes. Quantitative data involves taking measurements, while qualitative data are observations and descriptions of phenomena. When it comes to climate, scientists try to collect as much and as many types of data as possible to be able to analyze how climate is changing and what effects it is having. Because climate affects all areas of the world, collecting this data is a large undertaking. This is where you can help.

On our ever-changing Earth, conditions may change quickly or slowly. Some changes come from natural processes; some from human activity. Satellites allow us to see conditions and track changes over time — in land use, forest health, land/water interface, and so on. Since 1972, Landsat satellites have been collecting data using various portions of the visible and invisible electromagnetic spectrum, at a scale close enough to see highways, but not individual buildings on a city block.
