Measurements of climatic processes such as cold air drainage flows are problematic over mountainous areas. Observation of cold air drainage is not available in the existing observation network and it requires a special methodology. The main objective

In January 2000 nine snow sensors were deployed in Dronning Maud Land, Antarctica, along a 355 km transect from Kvitkuven near the shelf edge via the Finnish research station, Aboa, to the Amundsenisen plateau. The purpose was to test a sensor system

Sea ice surface topography data were obtained by helicopter-borne laser profiling during the First Finnish Antarctic Expedition (FINNARP-89). The measurements were made near the ice margin at about 73°S, 27°W in the eastern Weddell Sea on December

We analyzed the effect on the visible and near-infrared reflectance of shadows cast by a building, a conifer, and a hardwood on three different surfaces (grass, bare soil, and asphalt). Ground-measured radiances were collected with a radiometer measu

Shadowing is one of the factors that most affects the relation between canopy reflectance and forest light interception efficiency. For Christmas tree plantations, a decreasing exponential function can assess the shadow proportion from canopy SPOT-HR

Lack of thermal insulation of the ground by snow cover is the prime factor causing permafrost to occur in the alpine tundra areas near Schefferville (55°N, 67°W). Lack of protection by seasonal snow cover is also the prime factor suppressing the gr

Empirical studies using remotely sensed data to estimate forest stand parameters have shown that the biological variable which is most closely functionally linked to the spectral response of the canopy is the leaf area index (LAI). The LAI is highly

Net radiation represents a disequilibrium between incoming and outgoing radiative fluxes at a surface. This disequilibrium is caused by the non-radiative, i.e. the convective, conductive and chemical (mainly photosynthetic and respiratory) heat fluxe

In the Bothnian Experiment in Preparation for ERS-1 (BEPERS-88) airborne laser profiles and Synthetic Aperture Radar (SAR) images were obtained simultaneously over the pack ice in the Bay of Bothnia, Baltic Sea. The possibility of mapping ice ridging
