The false colour RGB composite Meteosat-8 image shown below clearly pinpoints the many severe forest fires raging in several parts of Portugal on 21 August 2005. In this composite image, red is assigned to the IR3.9 channel, which is particularly useful for the detection of fires and hot-spots. Channel 1 (VIS 0.6) is assigned a green colour and Channel 12 (HRV) blue. The HRV channel highlights a smoke plume heading out into the Atlantic, driven by a generally northeasterly wind in this region. The variability over time of the fires is clearly seen in the IR3.9 movie loop (see link under 'See also').
