NASA | Terra@10: Terra's 10th Anniversary

The video discusses NASA's Terra mission, launched in 1999, which observes Earth's land, water, and atmosphere. Terra's suite of instruments, including contributions from Japan and Canada, provides comprehensive data on Earth's climate and environment. Over a decade, Terra has enabled significant scientific discoveries, published in numerous journals, and has applications in agriculture, forest monitoring, and climate change studies. The mission has revealed the impact of fires and pollution on the atmosphere and climate, highlighting the role of aerosols in cloud formation and climate uncertainty. Terra's data helps scientists understand Earth's transformations and future implications.

What significant impact of fires did Terra reveal?

• Fires reduce the amount of sunlight reaching Earth

• Fires inject smoke high into the atmosphere, affecting air quality

• Fires have no effect on the atmosphere

• Fires increase ocean temperatures

How do particles from pollution affect clouds, according to Terra's findings?

• They have no effect on clouds

• They cause clouds to get smaller and reflect more sunlight

• They cause clouds to become larger

• They make clouds disappear
