ICESat-2 Por Los Números: 532

The Atlas instrument uses a laser with a specific color to measure Earth's elevation. It filters out sunlight to prevent overwhelming its detectors, allowing only light waves of 532 nanometers. Sunlight can also activate the detectors, so computer programs are used to filter out solar photons from the data.

What is the primary function of the Atlas instrument's laser?

• To analyze the Earth's atmosphere

• To capture images of the Earth

• To measure the elevation of the Earth

• To measure the temperature of the Earth

Why does the Atlas instrument need to filter out sunlight?

• To improve image quality

• To avoid overwhelming the detectors

• To save energy

• To prevent damage to the laser

What specific wavelength of light does Atlas allow to pass through?

• 450 nanometers

• 600 nanometers

• 532 nanometers

• 700 nanometers

What is the purpose of the computer programs used by Atlas?

• To increase the speed of data collection

• To filter out solar photons

• To adjust the laser's wavelength

• To enhance the laser's power

How do computer programs contribute to the accuracy of Atlas's data?

• By increasing the laser's range

• By filtering out unwanted solar photons

• By reducing the laser's energy consumption

• By enhancing the resolution of images
