Earth Observing System snow and ice products for observation and modeling



Snow and ice are the key components of the Earth's cryosphere, and their influence on the Earth's energy balance is very significant due at least in part to the large areal extent and high albedo characterizing these features. Large changes in the cryosphere have been measured over the last century and especially over the past decade, and remote sensing plays a pivotal role in documenting these changes. Many of NASAs Earth Observing System (EOS) products derived from instruments on the Terra, Aqua, and Ice, Cloud, and land Elevation Satellite (ICESat) satellites are useful for measuring changes in features that are associated with climate change. The utility of the products is continually enhanced as the lengths of the time series increase.
