European hot spots and fires identified from space   Hot spots across Southeastern Europe from 21 to 26 August 2007 have been detected with instruments aboard ESA satellites, which have been continuously surveying fires burning across the Earth’s surface for a decade. Working like thermometers in the sky, the Along Track Scanning Radiometer (ATSR) on ESA’s ERS-2 satellite and the Advanced Along Track Scanning Radiometer (AATSR) on ESA’s Envisat satellite measure thermal infrared radiation to take the temperature of Earth's land surfaces.   Haze of the smoke over Greece, covering in particular the area of Olympia. The image was acquired on 27 August 2007 by Envisat's Medium Resolution Imaging Spectrometer (MERIS) optical instrument, while working in Full Resolution mode to provide a spatial resolution of 300 metres.   On 24 August 2007 Envisat captures billowing smoke from fires raging across Greece's southern Peloponnese peninsula, where fires have claimed the lives of at least 60 people since they began.   Fires starting in Greece on 23 August 2007. The image was acquired by Envisat's Medium Resolution Imaging Spectrometer (MERIS) optical instrument, while working in Full Resolution mode to provide a spatial resolution of 300 metres.
