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.

How does the Atlas instrument measure the elevation of the earth?

What happens when sunlight activates the Atlas detectors?
