Forest fires in Portugal

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 Channel 4 (3.9μ) which is particularly useful for the detection of fires and hot-spots. Channel 1 (VIS 0.6μ) 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 movie loop (also Channel 4 (3.9μ), which runs from 18:00 UTC on 21st August to 08:00UTC on 22nd August.
