ICESat-2 Por Los Números: 1,387

The video tutorial discusses the orbital patterns that occur every 91 days, creating a dense mesh over the poles. This pattern, anchored at the Summit Observatory in Groen Landia, allows scientists to observe seasonal changes. Frequent measurements of the polar regions provide a detailed view of glacier retreat, melting ice sheets, and thinning sea ice, highlighting the global impacts of these changes.
