NASA's Trailblazing Satellites: Mapping Earth's Changing Climate

NASA's satellites are at the forefront of monitoring Earth's climate, providing invaluable data on the planet's changing conditions.


With climate change becoming an increasingly urgent issue, accurate and timely data is crucial for understanding its impacts and informing mitigation efforts.


NASA employs a variety of satellite instruments to observe Earth's climate, including sensors that measure temperature, sea level, ice extent, and atmospheric composition.


Satellites equipped with thermal sensors monitor changes in global temperature, helping scientists track trends such as rising temperatures and changing weather patterns.


Specialized radar altimeters aboard satellites measure changes in sea level, providing vital information about the rate of sea level rise and its implications for coastal regions.

Sea Level Rise

Satellites equipped with radar and laser altimeters monitor polar ice caps and glaciers, allowing scientists to track changes in ice extent and volume over time.

Ice Melt

Satellites equipped with spectrometers and other instruments measure key atmospheric gases, aerosols, and pollutants, helping scientists understand the complex interactions.


NASA combines satellite observations with computer models to simulate Earth's climate system, improving our understanding of past climate changes and predicting future trends.


NASA's trailblazing satellites play a critical role in mapping Earth's changing climate, providing essential data for policymakers, researchers.
