Radar satellite observations of snow surface roughness and hoar frost in Greenland

Radar satellite observations of snow surface roughness and hoar frost in Greenland

The Finnish Meteorological Institute organised a RASCALS measurement project which was carried out in Greenland's highlands in Summer 2010. The project involved taking measurements of snow surface roughness and reflectivity orientation. At the same time, pictures of the area were taken using the RADARSAT radar satellite. Using the images, it was possible to determine the surface roughness orientation and to observe frosting during the night. Both properties have an impact on weather developments.
