AIRS: NASA Advances Our Understanding of Earth’s Climate

The video discusses the Atmospheric Infrared Sounder (AIRS), a NASA instrument that revolutionized the study of Earth's atmosphere by analyzing infrared thermal radiation. Initially part of a weather mission, AIRS has provided unique climate data over 20 years, aiding in understanding climate change. The data reveals significant changes in the Arctic and tracks global air pollution and fire events. AIRS data is crucial for decision-making and will continue to offer insights into the climate system for future generations.

What is the primary function of the Atmospheric Infrared Sounder (AIRS)?

• To observe visible light from the sun

• To measure thermal radiation from Earth and the atmosphere

• To monitor ocean currents

• To track satellite movements

How has the role of AIRS evolved over time?

• From a satellite tracking mission to a climate mission

• From a space exploration mission to a weather mission

• From a weather mission to a climate mission

• From a climate mission to a weather mission

What significant changes have been observed in the Arctic according to AIRS data?

• Increased cloudiness and less water vapor

• Decreased temperatures and more ice

• Warmer temperatures and less ice

• More cloud cover and less water vapor

Which of the following is NOT a trace gas monitored by AIRS?

• Ozone

• Methane

• Carbon monoxide

• Nitrogen

How does AIRS data contribute to understanding flu spread?

• By analyzing atmospheric dryness

• By measuring ocean temperatures
