Final answer:
Satellite time series are used to monitor the cryosphere by tracking changes in ice extent, thickness, snow cover, and melt patterns. This information helps scientists understand the impact of climate change on the cryosphere.
Step-by-step explanation:
Satellite time series are being used to monitor the cryosphere, which includes ice sheets, glaciers, and sea ice. By analyzing satellite images over time, scientists can track changes in the extent and thickness of ice, as well as measure changes in snow cover and melt patterns. This information is pertinent to understanding the cryosphere because it allows scientists to assess the rate of ice loss, monitor changes in polar regions, and study the impact of climate change on the cryosphere.
