This Envisat image combines two Advanced Synthetic Aperture Radar (ASAR) acquisitions – one from 15 May and one from 19 June 2008 (before and after the fire) – in order to detect the extent of damages that occurred in Norway’s largest forest fire. The burnt area is visible as a red cluster in the image centre (top). Other reddish-coloured areas do not represent fire damage but rather changes that occurred between acquisitions.
