SPEXone: Dutch Instrument Arrives for PACE Mission

The video tutorial discusses the setup and purpose of the Specs One instrument, which measures the intensity and polarization of light reflected by atmospheric aerosols. These aerosols play a role in counterbalancing greenhouse gas warming, but their exact impact is uncertain, complicating climate change predictions. The video also highlights the design challenges faced in creating a compact, multi-viewing optical system for Specs One.

What is the primary purpose of the Specs One instrument?

• To track the movement of clouds

• To measure the temperature of the atmosphere

• To measure the intensity and polarization of light reflected by aerosols

• To analyze the chemical composition of aerosols

How do aerosols affect the warming caused by greenhouse gases?

• They amplify the warming effect

• They have no impact on the warming effect

• They completely negate the warming effect

• They counterbalance the warming effect

Why is it difficult to predict future climate change?

• Due to unpredictable weather patterns

• Because climate models are inaccurate

• Due to the lack of technology

• Because of the unknown impact of aerosols

What was a major challenge in designing the Specs One instrument?

• Ensuring it could withstand high temperatures

• Integrating it with satellite systems

• Designing a compact optical system for multi-directional light capture

• Making it lightweight for easy transport

How many directions does the Specs One instrument capture light from?

• Five

• Four

• Three

• Six
