Permafrost is found in about a quarter of the land area in the northern hemisphere. Unlike snow and ice cannot permafrost be "observed" with remote sensing techniques. However satellites collect data regarding permafrost from sensors in field, and permafrost can be modeled numerically using above-ground data sets of temperature and snow depth. In SatPerm we aim to see if such data sets can be used for modelling of permafrost.

Image of Mount Everest and the Khumbu icefall (left) in a green-red-near infrared ASTER satellite image. Snow and ice appear white, as also humans see it. Inset to the right: Part of the mountain and ice fall as seen with a satellite image that captures infrared light that show snow and ice in dark colours. Figure: A. Kääb.

A large international study - Global Land Ice Measurements from Space (GLIMS) shows that Earth’s glaciers are shrinking with only a few exceptions. The scientists behind the study have applied satellite images to study the glaciers over the recent decades. The comprehensive report is now published as a book and an e-book.

To better understand and describe the processes related to the Earth’s physical features and the society it is increasingly important to use remote sensing and geographical information systems (GIS) as tools for managing large amounts of spatial and geographically-referenced information.
