Polar regions are those surrounding the North and South Poles and situated within the Arctic and Antarctic Circles of the Earth. The polar regions are characterized by environments harsh to human and other organisms: low mean annual temperature and long nights and extensive snow and ice cover in winter. Because of the harsh conditions and poor accessibility, assessment of different aspects of the polar environment, such as light, temperature, snow and ice cover, soil and vegetation, largely relies on information acquired by remote sensors, i.e. airborne- and satellite-borne electromagnetic instruments. This article briefly describes how and to what extent polar environmental information is currently derived through remote sensing methods.
