Understanding the Discover AQ Campaign

NASA's Discover AQ campaign aims to measure and map air pollutants over Baltimore using a P3 aircraft and a high-flying UC2. The mission faces challenges in monitoring air quality from space, as satellites provide data for the entire atmosphere rather than surface levels. Discover AQ employs a three-pronged approach, collecting data from ground stations, low-flying P3, and high-flying UC2 to create a 3D view of pollutants. The operation faces challenges like air traffic and weather, but the potential rewards include better understanding of pollutant behavior and improved decision-making on emissions.

What is the main goal of NASA's Discover AQ campaign?

• To explore outer space

What is a significant challenge when using satellites to monitor air quality?

• Satellites are not available during the summer

• Satellites cannot detect pollutants

• Satellites provide data for the entire atmosphere, not just the surface

• Satellites are too expensive to operate

Why is it important to understand pollution levels at the surface?

• To improve satellite imagery

• To enhance aircraft performance

• To assess the impact on human health

What is the purpose of the three-pronged approach in the Discover AQ campaign?

• To reduce the cost of the campaign

• To create a three-dimensional view of pollutants

• To improve satellite technology

• To increase the speed of data collection

What is a unique aspect of the Discover AQ flights?

• They use only unmanned aircraft

• They are conducted in a major urban area

• They are the longest flights ever recorded

• They are conducted at night

What is a potential benefit of the Discover AQ campaign?

• Increasing satellite lifespan

• Making informed decisions about emissions

• Improving weather forecasts

• Developing new aircraft

How does the Discover AQ campaign help in understanding pollutant behavior?

• By altering weather patterns

• By increasing the number of satellites

• By showing how pollutants are chemically altered or transported

• By reducing the number of pollutants
